Abstract: A capacitance sensor formed of a plurality of laminated layers includes: a first conductive portion; a second conductive portion arranged to face the first conductive portion; a first conductive wiring in a layer identical to the first conductive portion; a second conductive wiring in a layer identical to the second conductive portion; and a flexible base material having a dielectric property and elasticity and arranged between the first conductive portion and the second conductive portion, wherein a third conductive wiring connecting the first conductive portion or the first conductive wiring to the second conductive portion or the second conductive wiring between layers is arranged on the flexible base material.

Abstract: A capacitance sensor made of a plurality of layers includes: a first layer including a first electrode; and a second layer including a second electrode and arranged to face the first layer, wherein at least one of the first layer and the second layer is an elastomer layer which is a dielectric and is made of an elastically deformable elastomer, and the elastomer layer is bonded by an adhesion layer formed by applying an elastomer in a pre-curing state that is a material identical to the first layer or the second layer and curing the elastomer.

Abstract: An electrostatic capacity sensor 1 capable of expanding a force detectable region includes an upper electrode 11, a lower electrode 11 for detecting electrostatic capacity C between the lower electrode 11 and the upper electrode 11, and a base material 12 having dielectric properties and elasticity and disposed between upper and lower electrodes 11 and 11. An upper base material layer portion 12a and a lower base material layer portion 12b of the base material 12 are configured such that elastic deformation amounts when the same force is applied are different from each other.
