リュームアップ効果が十分でないという問題がある。However, in the conventional method of processing the tip portion of the fiber in the mascara brush, the processing is performed on the entire circumference of the mascara brush 4. For this reason, when applying the mascara agent to the eyelashes using the mascara brush, the eyelashes do not sufficiently enter the inside of the mascara brush, the amount of the mascara agent adhering to the eyelashes is reduced, and the eyelashes are held to be entangled. There is a problem that the catch-up feeling and volume-up effect are not sufficient.

とができる。This mascara brush 4A has a region A in which the tip of the fiber 7 is bent and a region B in which the tip of the fiber 7 is not bent and the fiber 7 extends straight. And are alternately provided in the circumferential direction of the mascara brush 4A three times. As a result, when applying the mascara agent to the eyelashes using the mascara brush 4A, the region B that is not bent is applied.
Then, the eyelashes are the fibers 7 holding the mascara 2
In the region A in which the eyelashes easily enter the inside of the fiber and are bent, the eyelashes that enter the inside of the fiber 7 are caught and become difficult to come off from there, so that the eyelashes can be sufficiently coated with the mascara agent, and It is possible to improve the catch-up feeling due to the action of the region A in which the bending process is performed.

Since it is substantially the same as the case where the eyelashes are applied, and the circumferential length of the region B in which the eyelashes enter the inside of the fiber 7 cannot be sufficiently secured, it is preferably 5 or less, and particularly as shown in FIG. It is preferably 3 or 2. When the number of repeated regions A and B in the circumferential direction is small, it is easy to adjust the curl-up and volume as desired by changing the portion of the mascara brush 4A that is applied to the eyelashes.
