Abstract
A capacitive sensor includes a dielectric layer made of an elastomer and a pair of electrodes arranged via the dielectric layer, and detects deformation on the basis of electrostatic capacity variation between the pair of electrodes. The pair of electrodes contain an elastomer and conductive fillers filled into the elastomer, are expandable and contractible in accordance with deformation of the dielectric layer, and exhibit little conductivity variation even when the pair of electrodes expand and contract. At least one of the dielectric layer and the electrodes is formed by a printing method using a dielectric layer coating containing a formation component of the dielectric layer or an electrode coating containing a formation component of the electrode.
