The purpose is to reduce a load on fingers which grip a comb and to increase a gripping power to the fingers which grip the comb. In a comb (1), first and second recessed parts of a curved shape are formed in both perimeter edges of one-end edge comb part (3) and the other-end edge comb part (4) in width directions, respectively, and also first and second comb tooth recessed parts of a curved shape are formed in both perimeter edges of a plurality of comb teeth (6) in width directions. When one of the one-end edge comb part (3) and the other-end edge comb part (4) is mainly gripped by the fingers, the fingers are fitted into the first or second recessed part of the one-end edge comb part (3) or the other-end edge comb part (4) and also into the first or second comb tooth recessed parts of the comb teeth (6) located nearby. Since each of the recessed parts has the curved shape, it becomes in a surface contact to the fingers and, thus, the gripping power acting on the fingers is distributed and the load on the fingers is reduced, and also the gripping power increases due to the finger fitted into each of the recessed parts.
