Abstract
In an electrostatic capacity sensor 1, first electrodes 11a to 11d are provided on a substrate 10, and an electrode support 14 has dielectric properties and elasticity and is fixed to the substrate 10. A second electrode 12 is provided in the electrode support 14 so as to face the first electrodes 11a to 11d with a distance from the first electrodes 11a to 11d. The electrostatic capacity sensor has improved durability.
