PROBLEM TO BE SOLVED: To provide an ultraviolet irradiation apparatus for efficiently curing an ultraviolet curing member.SOLUTION: The ultraviolet irradiation apparatus includes: a plurality of light sources irradiating ultraviolet ray which are disposed; an irradiation part having a first irradiation part and a second irradiation part; and a first condenser lens which is disposed to overlap a plurality of the light sources disposed in the first irradiation part when observed from a direction of irradiating the ultraviolet ray of the light sources. An irradiation intensity of the ultraviolet ray obtained by irradiating from the first irradiation part and focusing on the first condenser lens is stronger than the irradiation intensity of the ultraviolet ray irradiated from the second irradiation part.
