Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a blade for wind power generation capable of restricting damage caused by thunderbolt to minimum.SOLUTION: An opening part 6 is formed at a blade surface between a leading edge 8 and a trailing edge 9 of a blade main body 4 of hollow structure, a removable member 7 closing the opening part 6 is fixed to the blade main body 4 through a tapered part 71 and an outer peripheral end part 72, the tapered part 71 and the outer peripheral end par 72 have the removable member 7 fixed to the blade main body 4 in such a way the removable member 7 is removed from the blade main body 4 with a part being left to release the opening part 6 in response to an increase pressure in the hollow part 12 of the blade main body 4, the tapered part 71 is made of flexible material for keeping the fixed state for the blade main body 4 with a part of the removable member 7 being not removed when the removing is carried out.
