摘要： To provide a vehicle lamp in which it is possible to prevent a bonding wire from blocking light emitted from a light emitting surface while improving heat dissipation performance from a light emitting portion. A vehicle lamp includes a light emitting portion having a light emitting element, a circuit board, and a heat sink. In this vehicle lamp, a front region of the heat sink is divided into a first region and a second region, the light emitting portion is fixed to the first region, and the circuit board is fixed to the second region. A light emitting portion-side terminal provided in the light emitting portion and a board-side terminal provided in the circuit board are electrically connected by a bonding wire. The light emitting portion-side terminal is disposed between a light emitting surface that covers the light emitting element, and the board-side terminal in front view.

摘要： A vehicle lighting unit ensures support rigidity of a substrate connection part in the front-rear direction without increasing components. The vehicle lighting unit includes a light source part, a power feeding member, a heat dissipation member, and a socket. The light source part has a light-emitting element, and a substrate connected to the light-emitting element. The power feeding member supplies power to the light source part. The heat dissipation member is mounted with the light source part. The socket is assembled on the rear side opposite to the front surface of the heat dissipation member mounted with the light source part. In the vehicle lighting unit, the substrate and the power feeding member are electrically connected by the substrate connection part. The heat dissipation member integrally has an extension support unit that supports at least the substrate connection part in placement in a front-rear direction of the heat dissipation member.
