A transformer is accommodated in a case body having reduced size. The transformer includes a primary bobbin, a primary coil wound around the primary bobbin, a secondary bobbin combined with the primary bobbin such that the primary coil surrounds the secondary bobbin, and a secondary coil wound around the secondary bobbin. Primary and secondary terminals are respectively connected to the primary and secondary coils such that the primary terminal projects in the same direction as the secondary terminal.

Transformer and method of assembling same

A motor vehicle headlamp in which electromagnetic waves generated when the discharge bulb employed therein as the light source is activated are prevented from leaking out of the headlamp and interfering with other circuitry on the vehicle. The lamp body of the headlamp is made of a conductive material, or an insulating resin coated with a conductive layer. The lamp body or conductive layer is grounded to the body of the vehicle, thereby to ground out potentially interfering electromagnetic waves generated inside the lamp body.
