摘要： A planar heating element 1A comprises a resin-film 10 and a heating portion 20A that comprises a conductive circuit 30A formed on the resin-film 10. The resin-film comprises at least one of openings 11A-11F or the recesses 12A-12G surrounding a specific point SP located on the resin-film. The openings 11A-11F are located outside of a circular region CA of a predetermined radius centered at the specified point SP and are located within the conductive circuit 30A. The recesses 12A-12G are recessed toward an inside of the resin-film 10 and are located on an outer edge of the resin-film 10.

摘要： A capacitance sensor (1) includes a base film (10) having translucency, a resist layer (20) provided on a part of one main surface (11) of the base film (10), the resist layer (20) having translucency and having higher adhesion to a predetermined conductive polymer than the base film (10), and electrodes (31 to 36) having translucency and made of a conductive material containing the predetermined conductive polymer, at least a part of each of the electrodes (31 to 36) being provided on a surface of the resist layer (20) opposite to a surface thereof provided with the base film (10). When viewed along a thickness direction of the base film 10, a region (15) of the main surface (11) of the base film (10) not provided with the resist layer (20) surrounds the electrodes (31 to 36).

摘要： A sensor device 1A includes: an insulating substrate 11; a touch sensor TS that includes a sensor electrode 12 disposed on a first surface 15a disposed on an operation surface side; a shield electrode 131 disposed on the first surface 15a; and a detecting electrode 14 facing the shield electrode 131 and disposed on a second surface 15b different from the first surface 15a. The first surface 15a is located closer to the operation surface than the second surface 15b, the shield electrode 131 and the detecting electrode 14 constitute a pressure-sensitive sensor that detects a change in capacitance value caused by approaching of the shield electrode 131 and the detecting electrode 14, and the shield electrode 131 blocks capacitive coupling between an operator FIN and the detecting electrode 14 caused by approaching of the operator FIN to the operation surface.

摘要： A load detection sensor (5A) includes: a first electrode sheet (6) including a first electrode (62); a second electrode sheet (7) including a second electrode (72) opposed to the first electrode (62); a spacer (8) interposed between the first electrode sheet (6) and the second electrode sheet (7), the spacer (8) having an opening (81) between the first electrode (62) and the second electrode (72); an annular member (9) disposed in the opening (81); and an adhesive layer (10) disposed at least either between the spacer (8) and the first electrode sheet (6) or between the spacer (8) and the second electrode sheet (7). The annular member (9) is in contact with at least one of the first electrode sheet (6) exposed at the opening (81) and the second electrode sheet (7) exposed at the opening (81), and has no adhesion to both of the first electrode sheet (6) and the second electrode sheet (7).
