Abstract
An electronic flash device which is protected from thermally damaging a lamp holder (30) supporting a flash tube (40) even when the flash tube is lighted in a consecutive manner for a prolonged period of time. The lamp holder is made of ceramic material. The flash tube is supported by the lamp holder via a tube mounting member (44) which includes a wavy central part (44A) extending laterally along a back side of the lamp holder and a pair of annular parts (44B) fitted on either axial end of the flash tube such that the flash tube is resiliently urged against a bottom part of a concave mirror (42) received in the lamp holder.
