There is provided a vehicle lighting device employing a plurality of light-emitting diodes (1) as light sources. Mount pads are provided on a light-emitting diode mount surface (21) of a circuit board (2). On the circuit board (2), the mount pads (40) are provided on both sides of a plurality of pairs of through-holes (20). When two leads (12,13) of the light-emitting diode (1) are inserted into the pair of two through-holes (20), respectively, and the light-emitting diode (1) is mounted to the mount pads (40) on the both sides, an air vent space is formed which is defined by the light-emitting diode (1), the circuit board (2), and the mount pads (40) on the both sides. Accordingly, air comes out smoothly of the through-holes (20) via the space (42) when solder (3) is entered the through-holes (20) in an automated soldering process. This allows the light-emitting diodes (1) to be disposed in place relative to the circuit board (2). Furthermore, it is ensured that the leads (12,13) of the light-emitting diodes (1) and conductive traces of the circuit board (2) are connected to each other via solder (3). <IMAGE> |
