In a casing (3) of a headlamp, a substrate portion (7) to which a light-emitting diode (13) as a light source is mounted, and a battery case (9) accommodating a battery (11) for providing necessary power to the light-emitting diode (13) are provided. The substrate portion (7) is spaced apart from a partition (10) disposed on the front side of the battery case (9), with spacing (8) provided therebetween. The partition (10) is provided with a vent hole (20), having an upper vent hole (20a) and a lower vent hole (20b), for establishing communication of the spacing (8) between the substrate portion (7) and the partition (10) with the space within the battery case (9), 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. <IMAGE> |
