ABSTRACT:
In a casing of a headlamp, a substrate portion to which a light-emitting diode as a light source is mounted, and a battery case accommodating a battery for providing necessary power to the light-emitting diode are provided. The substrate portion is spaced apart from a partition disposed on the front side of the battery case, with spacing provided therebetween. The partition is provided with a vent hole, having an upper vent hole and a lower vent hole, for establishing communication of the spacing between the substrate portion and the partition with the space within the battery case, for circulation of the air. Thus, a headlamp capable of suppressing adverse effects of the heat generated from the light-emitting diode or the like on the elements mounted on the substrate is provided.
