PROBLEM TO BE SOLVED: To provide an ultraviolet ray irradiation apparatus capable of uniformalizing the intensity distribution of the ultraviolet ray and giving sufficient ultraviolet irradiation intensity even in an end part of an ultraviolet lamp. SOLUTION: Flat additional reflective plates 13, 13 each having a reflection surface vertical to the extending direction of the ultraviolet lamp 11 are arranged on an opening part side of a light collecting reflector 12 for reflecting and collecting the ultraviolet ray from the ultraviolet lamp 11 to collect the direct light, which is diffused to the outside of an opening part from the ultraviolet lamp 11, to the inside of a conveyer belt 40.
