Abstract
A sensor that includes a switch unit and that detects a pressure applied from the front side to the switch unit or a finger approaching the switch unit from the front side is located on the back side of upholstery. A base member has a protruding portion on its surface. The upholstery includes: a light-transmitting region that is located over a light guide portion of the base member and the switch unit of the sensor and that allows light from a light source to transmit therethrough to the front side; and a non-light-transmitting region that blocks the light from the light source. A raised portion that is raised on the front side of the upholstery is located near the light-transmitting region in the non-light-transmitting region of the upholstery. The protruding portion of the base member is placed in the raised portion from the back side of the upholstery.
