PROBLEM TO BE SOLVED: To provide an exposure apparatus for a fluorescent face of a color cathode ray tube which can reduce the dispersion of the intensity of radiation when the dispersion of the intensity of radiation is generated in a light beam irradiated through a slit of slit plate, as the relative position relationship of a high-pressure mercury lamp and the slit plate is maintained in non-parallel state. SOLUTION: A negative electrode 20 of a high-pressure mercury lamp 12, of which a positive electrode 19 is fixed to a positive electrode holder 18, is held at a negative electrode holder 21 having a concave shaped engagement portion 22, therefore the relative position relationship of the high-pressure mercury lamp 12 and the slit plate 27 can be maintained in parallel state.
