Abstract: A wind power generation tower for supporting a wind power generator in mid-air includes a tower lower portion that includes at least three legs made of hollow concrete and erected on a foundation so as to tilt toward each other, a tower intermediate portion arranged in a center of the at least three legs in a plan view, and a tower upper portion protruding upward from the tower intermediate portion to support the wind power generator. The tower intermediate portion is made of cone-shaped hollow concrete, and includes a lower end supported by the legs and an upper end thinner than the lower end. The tower upper portion is made of a steel pipe, and includes a lower half portion supported by the upper end of the tower intermediate portion and an exposed body portion.
