Since the cosmetic brush 1 employs the deformed core wire 3i as a core material, the bristles 5 sandwiched therebetween are extended by receiving a predetermined restraining force from the deformed core wire 3i. . Since the deformed core wire 3 i has a “surface” in the circumferential direction, when the deformed core wires 3 i and 3 i are twisted together, the “surface” of the deformed core wire 3 i appears in the twisted portion 4. Since the bristles 5 extend in contact with the surface of the deformed core wire 3i, the extending direction is determined according to the contacted surface (if the core wire 3 is circular, there is no such surface, Extending randomly).

Therefore, the eyelashes 11 with a bundled feeling are made.

Further, in the cosmetic brush 1 of this embodiment, since the bristles 5 are broken into two, the deformed core wire 3i is not exposed, the coating liquid 12 remains around the deformed core wire 3i, and the coating liquid 12 is excessively applied.
