Abstract
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.
