摘要： A method for manufacturing a near-infrared sensor cover includes arranging a mask in a region of an undercoating layer formed on a rear surface of a base, the region being different from a heater formation region in which a heater is to be formed and different from a belt-shaped separation region extending along an edge of the heater formation region, forming a heat-generating film on the mask and the undercoating layer, the heat-generating film being made of the conductive heat-generating material, peeling, using a laser, the heat-generating film formed in the separation region, and removing the mask and the heat-generating film formed on the mask. The separation region has a width that is set to be smaller than a beam diameter of each of near-infrared rays transmitted from the transmitting portion.

摘要： In a cover device for a near-infrared sensor, a plate-shaped cover is arranged in a vehicle such that near-infrared light transmitted from a near-infrared sensor passes through the cover in the thickness direction. A part of the cover in the thickness direction is constituted by a bright decorative layer, which reflects part of incident visible light and allows near-infrared light to pass through. The cover is configured such that the near-infrared light transmittance is higher than the visible light transmittance. The vehicle further includes a light emitting portion, which emits visible light to the cover.

摘要： A decorative component for a vehicle includes a decorative body portion having millimeter wave transmittance and a heating sheet. The decorative body portion is configured to decorate the vehicle by being attached to part of a vehicle on a leading side in a transmitting direction of millimeter waves from a millimeter wave radar device. The heating sheet includes a plastic sheet and a wire-shaped heater provided on the plastic sheet. At least a main portion of the heating sheet is provided integrally with the decorative body portion. The thickness in the front-rear direction is set uniform in at least a transmittance area of millimeter waves in the decorative body portion and the heating sheet.

摘要： A vehicle decorative part includes a decorative main body and a heater. The decorative main body is configured to be attached to a vehicle at a front side in a transmission direction of millimeter waves from a millimeter wave radar and has a millimeter wave transparency. The heater has a heating element that emits heat when energized. At least a part of the heating element is located in an irradiation region of the millimeter waves in the heater. As a millimeter wave attenuation reducing configuration that reduces attenuation of the millimeter waves passing through the heater, the heating element is incorporated in the heater in a condition where an area proportion of an area of a section of the heating element that occupies the irradiation region to an area of the irradiation region is set such that an attenuation amount of the millimeter waves is less than or equal to a permissible value.

摘要： A radio-wave transmitting cover is configured to be arranged in the path of the radio wave of a radio-wave radar device. The thickness of the cover is set to a reference thickness at a reference position where the incident angle of the radio wave from the radio-wave radar device is 0°. The reference thickness is set to a value obtained by multiplying half of the wavelength of the radio wave by an integer. In the area around the reference position, the thickness of the cover is gradually changed such that the greater the distance from the reference position, the greater becomes the difference by which the thickness of the cover is larger than the reference thickness.

摘要： A vehicle sensor unit includes a millimeter wave radar device, an infrared sensor that is arranged at a position adjacent to the millimeter wave radar device, and a cover having a first cover portion and a second cover portion. The first cover portion is located in front of the millimeter wave radar device in a transmission direction of the millimeter waves to conceal the millimeter wave radar device and has millimeter wave transparency. The second cover portion is located in front of the infrared sensor in a transmission direction of the infrared light to conceal the infrared sensor and has infrared light transparency. The millimeter wave radar device and the infrared sensor are attached to the cover so that the whole vehicle sensor unit is configured as a single unit.
