Abstract
The capacitance sensor 1 includes a self-capacitance electrode 5, first electrodes 3 (3(1) to 3(4)), and a second electrode 4 which are arranged being separated from each other in a thickness direction of an elastically deformable base material 2 formed by a dielectric. The self-capacitance electrode 5 is connected to a first connection portion 10a for measuring capacitance by a self-capacitance method and a grounded second connection portion 10b via a switch 10 so as to be selectively connected to the first connection portion 10a and the second connection portion 10b.
