An illuminated push button unit includes a light-guide lens, a lens holder and a push-down control. The light-guide lens is configured to guide light from a light source to a light emission face disposed at a front end of the light-guide lens and emit the light from the light emission face. The lens holder is attached to the light-guide lens. The lens holder includes a light emission window through which the light emission face of the light-guide lens emits the light. The push-down control is attached to the light emission face in a middle of the light emission face so that the light emission face emits the light in an annular shape.
