A remote control transmitter is capable of performing remote control reliably with an inexpensive structure, in which a light-emitting element having an approximately bombshell-shaped translucent body including translucent resin and a lighting element main body incorporated in the rear part of the translucent body are provided in the front surface of a remote controller main body. The light-emitting element emits a light beam with a signal superimposed thereon when an operation part on the remote controller main body is operated, and an angle widening unit for widening the projection angle of the light beam emitted from the light-emitting element on the optical axis of the light beam is provided. The angle widening unit includes an inwardly tapered hole recessed in the front surface of the translucent body and a half mirror formed on the inner peripheral surface of the tapered hole, in which the angle widening unit reflects the light beam at the half mirror in order to widen the projection angle of the light beam.
