An illuminated switch includes an operation knob that includes an operation surface, a light source that emits light beams using a predetermined direction as an optical axis, and a first light guide member that is provided in the operation knob and guides the light beams emitted from the light source to the operation surface. The first light guide member includes a light incident surface formed of inclined surface that refracts light beams entering along the optical axis in a first direction, a reflection surface that reflects light beams refracted at the light incident surface in a second direction different from the first direction, and a light exit surface that transmits light beams reflected by the reflection surface.
