This capacitive switch device comprises: an operation panel (111) whereon a touch operation is carried out by a user; a film member (113a) provided in such a manner as to follow the surface on the side facing away from the side whereon the touch operation of the operation panel is carried out; and an electrode portion (113b) and wiring portions (113c, 113d) provided on the film member and forming, together with a finger of the user, a capacitor therebetween. The film member is pasted onto the operation panel at a predetermined first site of the film member by a pressure-sensitive adhesive (114), while being supported at a second site of the film member, which is different from the first site, by a support part (115) allowing for movements caused by thermal expansion and thermal contraction in the plane direction of the film member. In this manner, lifting of the film, which accompanies temperature variation, can be suppressed. |
