This wig fastening tool is formed by connecting and fixing two substantially U-shaped members to each other. Each substantially U-shaped member is constituted of a comb-teeth fixation piece (11) having comb teeth (20) fixed thereto and two curved elastic shanks (12 and 13) extending in the same direction substantially perpendicularly from the opposite ends of the comb-teeth fixation piece. In a state where openings (15) of the two substantially U-shaped members face each other and the curved elastic shanks (12 and 13) thereof overlap each other, the two substantially U-shaped members are fixed to each other at a plurality of fixation locations distributed in the direction in which the overlapping curved elastic shanks (12 and 13) extend. Thus, the two members have high elastic deformability and high unity. In a case where the wig fastening tool (S) is manually recurved, if one of the substantially U-shaped members (10) recurves, the other substantially U-shaped member (10) would always recurve likewise (i.e., only a single recurving operation is sufficient).
