    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： Provided is a proximity sensor that can limit degradation in voltage resistance. A proximity sensor 1 comprises: a housing 10; a coil unit that is accommodated in one end of the housing 10; a clamp 20 that is connected to the other end of the housing 10; a substrate 30 that has a circuit mounted thereon, such circuit being electrically connected to the coil unit; a shield 45 that covers a portion of the substrate 30 which is located on the housing 10 side; and a resin which is provided inside the housing 10 and the clamp 20, and which covers at least a portion of the substrate 30. The shield 45 extends to the inside of the clamp 20, and has an extension section 452 that covers at least a portion of the circuit that is located inside the clamp 20.
