Abstract
To provide a light-emitting unit for a door mirror capable of improving a stability of LED's position and connectivity, while reducing a breakage possibility of the LED due to heat. The light-emitting unit for a door mirror is characterized in that it includes a rigid first substrate part having a connector part to receive a signal, and mounts a control unit thereon to cause an LED to emit light based on the signal; a rigid second substrate part provided separately from the first substrate part and mounts the LED thereon; and a connection part connecting the first substrate part to the second substrate part and having a circuit to cause a current signal transmitted from a first substrate part side to reach the LED's side, and the connection part has lower heat transfer rate than heat dissipation rate of the second substrate part.
