Abstract
A capacitive switch device includes an operation panel operated by a user with a touch operation, a film member provided along a surface of the operation panel on an opposite side from a surface operated with the touch operation, and an electrode portion forming a capacitor with a finger of the user and a wiring portion, both the electrode portion and the wiring portion being provided to the film member. The film member is bonded to the operation panel by a pressure-sensitive adhesive at a predetermined first portion of the film member and supported at a second portion of the film member different from the first portion by a supporting portion which allows the film member to move due to thermal expansion and thermal contraction in an in-plane direction of the film member.
