Abstract:
The objective of the present invention is to provide a vehicle lamp with which it is possible to prevent a bonding wire blocking emitted light from a light emitting surface, while improving heat dissipation performance from a light emitting portion. The vehicle lamp is provided with a light emitting portion (31) including a light emitting element, a circuit board (32), and a heat sink (4). In the vehicle lamp (1), a front surface region of the heat sink (4) is divided into a first region (41) and a second region (42), the light emitting portion (31) is fixed to the first region (41), and the circuit board (32) is fixed to the second region (42). Light emitting portion-side terminals (31b) provided on the light emitting portion (31) and board-side terminals (32d) provided on the circuit board (32) are electrically connected by means of bonding wires (33). In a front view, the light emitting portion-side terminals (31b) are disposed in positions between a light emitting surface (31e) covering the light emitting element, and the board-side terminals (32d).
