PROBLEM TO BE SOLVED: To improve sensitivity of an electrostatic capacity type switch, and restrain a wrong operation of the switch.SOLUTION: An electrostatic capacity type switch comprises: an operation plate 10 forming operation faces 11a, 11b contact-operated by a finger tip F (operation body) of a user; and an electrode plate 20 arranged to the operation plate 10 on a side opposite to the operation faces 11a, 11b. Furthermore, the electrostatic capacity type switch is turned on and off according to a change of an electrostatic capacity generated between the finger tip F and the electrode plate 20. Then, the operation plate 10 is integrally formed of resin by multi-color molding a plate-like substrate 13 and high dielectric constant materials 15, 16 with a higher dielectric constant than that of the substrate 13. The high dielectric constant materials 15, 16 are arranged in a projection range 13a of the electrode plate 20. |
