Abstract: An electromagnetic shield includes a plate-shaped base and first projecting portions. The base has a first surface and a second surface, the first surface being configured to allow an electromagnetic wave to be incident on the first surface. The second surface is distant from the first surface and extends along the first surface. The electromagnetic shield includes a dielectric. In the electromagnetic shield, at least one of the first projecting portions has a side including a first point and a second point, the side makes different inclination angles with a projecting direction of the first projecting portion at the first point and the second point. In the projecting direction of the first projecting portion, the second point is closer to the first surface-than the first point is. On the side, an inclination angle β is greater than an inclination angle α.

Abstract: A member supplying sheet provided includes: a protective cover member configured to be placed on a face of an object to prevent a foreign matter from entering an opening of the face; and a substrate sheet having a surface where the protective cover member is placed. The protective cover member includes a laminate including: a protective membrane having a shape configured to cover the opening when the protective cover member is placed on the face; and an adhesive layer. The protective cover member is placed on the surface of the substrate sheet via the adhesive layer. The member supplying sheet is suitable for supplying the protective cover member to a device that picks up the protective cover member in a state where the substrate sheet is pushed up from a back side of the substrate sheet, the back side being opposite to the surface.

Abstract: Provided is a wiring circuit board that allows the electrical connection between the elements and the terminals to be easy and sure. The wiring circuit board includes an insulating base layer, a plurality of wires with different thicknesses from each other, and an insulating cover layer sequentially toward an upper side. The wires include a first wire having the greatest thickness. The wiring circuit board further includes a plurality of terminals disposed on an upper surface of the insulating base layer. The terminals are electrically connected with the wires, respectively. The upper surfaces and of the terminals are each located at an upper side as compared to an upper surface of the insulating cover layer (a wire covering portion) covering the first wire.

Abstract: An inductor includes a wire, and a magnetic layer covering the wire. The wire includes a conducting line and an insulating layer. The magnetic layer contains an anisotropic magnetic particle and a binder. In a peripheral region of the wire, the magnetic layer includes an orientated region. The peripheral region is, in a cross-sectional view, a region from an outer surface of the wire to an outward distance of 1.5 times an average of the longest length and the shortest length from the center of gravity of the wire to the outer surface of the wire. The upper surface of the inductor has a protruding portion caused by the wire.
