a light emitting base part configured to be pressed and operated by an operator and having optical transparency; and
a button body part configured to be molded as one body with the light emitting base part, the button body part including: a fixed leg part configured to elastically support the light emitting base part; a push-in column configured to apply pressure to a switch; and a light shielding wall part configured to protrude on a back side of the light emitting base part, and having a frame shape, wherein
the light shielding wall part is formed at a position corresponding to an outer shape of the light emitting base part, the position being inside with respect to the fixed leg part and the push-in column, in a plan view, and
the push button illumination structure is configured to cause light emitted from a light source arranged inside with respect to the light shielding wall part in the plan view to be reflected by an inner surface of the light shielding wall part.
