CAPACITANCE DETECTION TYPE INPUT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a capacitance detection type input device capable of detecting depression by a proper load at a predetermined position on a circumference.

SOLUTION: A capacitance detection type input device 101 includes: a flexible substrate 10; a conductive rubber 20 superposed on the flexible substrate 10; a metal or resin ring-shaped movable plate 30 integrated with the conductive rubber 20; and a frame 50 and a reinforcement plate 40 fixing the conductive rubber 20 superposed on the flexible substrate 10. The conductive rubber 20 includes a tapered portion 22 facing a fixed electrode 61 and a Z-axis direction detection electrode 62 through an insulator layer 11. The fixed electrode 61 is composed of plural arcuate fixed electrodes. Each of the arcuate fixed electrodes is composed of plural comb-shaped electrodes extending outward in a radial direction and connections connecting the comb-shaped electrodes with one another at positions closer to an inner periphery.
