PROBLEM TO BE SOLVED: To provide the applying method and curing method of a sealing agent which is capable of curing an ultraviolet curing type resin contained in the sealing agent up to a deep part with ultraviolet ray emitted from an ultraviolet curing unit to solve the problem that a gas is expanded to push up the sealing agent from the inside to cause hem swelling.SOLUTION: In the applying method of a sealing agent to a part between metal members configured so that air expanded in a heated state flows out, the sealing agent comprising an ultraviolet curing type resin containing polymerization initiators reactive with two or more kinds of ultraviolet rays having different peak wavelengths as a main component is applied and a holding means holding an ultraviolet irradiation unit for irradiation with the ultraviolet ray corresponding to each polymerization initiator is moved on the track of the coating means to cure the ultraviolet curing type resin. |
