Input device
An operation pad ( 20 ) has an exterior plate ( 21 ) having a light-emitting unit (E 1 ) and a touch sensor substrate ( 22 ) attached to the rear surface of the exterior plate ( 21 ). In addition, the operation pad ( 20 ) has a light source (S 1 ) attached to the rear surface thereof and a light diffusion member (H 1 ) that is an optical path through which light of the light source (S 1 ) passes toward the light-emitting unit (E 1 ). According to the structure, the structure for allowing the light-emitting unit provided on the operation pad to shine can be downsized.
