ABSTRACT:
A discharge lamp unit in which a pair of terminal and lead support assemblies (A, B), composed of a pair of metal connector terminals (123, 125) and a pair of metal lead supports (122, 124), are fixedly held by a molded resin lamp holder (120) in such a manner that the connector terminals (123, 125) extend from the rear surface of the lamp holder while the lead supports (122, 124) extend from the front surface of the lamp holder to support a discharge lamp (110). The lamp holder has an axial through-hole formed therein during the molding of the lamp holder in a metal mold in such a manner that the axial through-hole is located between the connector terminals of the terminal and lead support assemblies, whereby the lamp holder is enhanced in dielectric strength.
