To provide a stopper for a wig which does not utilize the curvature inversion of an elastic board attributable to strain but utilizes the curvature inversion of a curved elastic board in a natural state.

A stopper for a wig is composed of an inner comb 1 and an outer comb 2. In an inner comb 1, teeth 12 are protrusively placed in a roughly parallel state on a curved face of a curved thin board 11 and provided with fixing pieces 14 at both the ends. In an outer comb 2, teeth 22 are protrusively placed on a curved face of a curved narrow thin board 21 imparted with elasticity, so as to be engaged with the teeth 12. The outer comb 2 is overlapped on the curved concave of the inner comb 1, and slits 23 long in the longitudinal direction are formed on the both ends of the outer comb 2 to enable the moving of the connecting parts. Thus, both the combs are connected to each other.
