A thermoelectric conversion unit can easily be attached to and detached from a heater, in which lower electrodes are formed on the upper surface of a lower substrate, placed in opposition to an upper substrate, on the lower surface of which are formed upper electrodes; end faces of thermoelectric elements are bonded to both the electrodes to form a thermoelectric conversion module. A heat-absorbing member having a protruding engagement portion is installed on one of the substrates of the thermoelectric conversion module, and a heat-releasing member is installed on the other substrate, to form a thermoelectric conversion portion. A heat-conducting portion having a engagement hole portion is installed on the outer peripheral surface of a lamp, to form the light-source lamp portion. By engaging the protruding engagement portion with the engagement hole portion, the light-source lamp portion can be detachably attached to the thermoelectric conversion portion. The reflector, heat-absorbing member and heat-releasing member are formed from aluminum or an aluminum alloy.
