Abstract: A structure body includes: an electromagnetic wave detector; and a pair of arm portions that are positioned on both sides with the electromagnetic wave detector interposed therebetween. The electromagnetic wave detector includes a temperature detection element and an electromagnetic wave absorber which covers at least a part of the temperature detection element. Each of the arm portions includes a wiring layer which is in a line shape and electrically connected to the temperature detection element, and protective layers, a part of each of which is disposed on corresponding one of both sides of the wiring layer. The protective layers are made of a material having a lower thermal conductivity than the wiring layer. In a short direction of the protective layers in a plan view, the wiring layer is positioned on an inward side of both end portions of the protective layers in the short direction.

Abstract: The present disclosure includes an electromagnetic wave detector, and a pair of arms that are positioned on both sides with the electromagnetic wave detector interposed therebetween. The electromagnetic wave detector includes a temperature detection element, and electromagnetic wave absorbers which cover at least a part of the temperature detection element. The structure body has a structure in which the electromagnetic wave detector is hung or suspended with respect to a substrate facing the electromagnetic wave detector via the pair of arms. Area of a surface of the pair of arms on a side facing the substrate are larger than area of surface thereof on a side opposite to the side facing the substrate.

Abstract: A thermistor element includes: a thermistor film; a pair of first electrodes in contact with one surface of the thermistor film; an insulation film opposite to a contact side of the pair of first electrodes, the contact side on which the pair of first electrodes is in contact with the thermistor film; and at least one opening portion located in a region which overlaps each of the first electrodes when viewed in a plan view and passing through the insulation film. Each first electrode has a first portion located where each of the first electrodes and the opening portion overlap when viewed in a plan view and a second portion outside of where each of the first electrodes and the opening portion overlap when viewed in a plan view and is over the first portion and second portion to be in contact with the one surface of the thermistor film.
