A double-wrap band brake comprises a middle band with a frictional surface on the inner peripheral side, and a pair of outer bands coupled to this middle band and having frictional surfaces on the inner peripheral sides, an anchor bracket, and an apply bracket. The middle band has a first frictional member and a second frictional member disposed on an end portion of the apply bracket and thinner than the first frictional member, and an oil groove extending in the axial direction and between the first frictional member and the second frictional member. The first frictional member has a dynamic pressure groove opened to the oil groove and extending in the circumferential direction.
