Abstract
A capacitance sensor 1A in which first electrodes 3(1) to 3(4) and a second electrode 4 are arranged on a base material 2 made of a dielectric includes grounded electrostatic shielding members (5(1) to 5(6)). The electrostatic shielding members 5 are arranged, for example, at positions between first wiring portions 6(1)in, 6(2)in, 6(4) in connected to the first electrodes 3(1), 3(2), 3(4) and the second electrode 4, at a position between a second wiring portion 6(5)in connected to the second electrode 4 and the first electrode 3(4), and at a position between the second wiring portion 6(5)in and the first wiring portion 6(4)in.
