The present invention provides a technique for minimizing degradation in design quality while maintaining ease of use. A securing member is arranged on the operation-surface side of a touch panel, and a cover panel is arranged on the operation-surface side of the securing member. The cover panel is provided with a cover panel through-hole, and the securing member is provided with a securing member through-hole that is wider than the cover panel through-hole. A push-button part is arranged inside the cover panel through-hole. The push-button part includes a depression part, and a switch part including a base part and a switch surface part. The base part is arranged inside the securing member through-hole between the cover panel and the touch panel, and the switch surface part protrudes from the inner edge of the base part toward the cover panel through-hole. The depression part is secured to the switch surface part from the side opposite the touch-panel side. |
