Abstract
A graphic that indicates a switch is formed on a panel at a location corresponding to a first light guide element. A character to be displayed via the panel is formed on a second light guide element. The first light guide element is supported on a substrate, in close contact with an electrode, via a sheet-like shaped attaching member, and the second light guide element is supported by a base material without being supported on the substrate.

- a cover portion including a panel cover on which a graphic indicating a switch is formed;
- a first light guide element configured to face the panel cover at a location at which the graphic is formed;
- a first light source provided corresponding to the first light guide element;
- a second light guide element on which a specific graphic to be displayed via the panel cover is formed and configured to face the panel cover;
- a second light source provided corresponding to the second light guide element;
- an electrode provided at a location corresponding to the first light guide element and configured to detect a capacitance;
- a substrate on which at least the first light source and the electrode are mounted;
- and
- a base member configured to detachably support the second light guide element and to be jointed with the cover portion,
- wherein the first light guide element is supported on the substrate at a location of the electrode and the second light guide element is supported by the base member without being supported on the substrate.
