Abstract: Provided is a tool for applying cosmetics for mascara and eyebrow cosmetics which allows applying a liquid cosmetic in an appropriate amount to eyelashes or eyebrows, and with which a previously unexperienced feeling of use can be obtained. In an application tool (1) for which a plurality of bristles (30) are fixed in a double-folded manner to the inside of a long groove (12), which is formed at a partial side surface of a brush portion (10) formed at a leading end side of a brush shaft (6), comb teeth (26) are integrally formed at a predetermined pitch in a brush portion axial direction on an exposed surface (21) of the fastener (20). As a result of forming the comb teeth (26) in a space that is wide between two lines of bristle groups (30a, 30b), the liquid pool space is narrowed accordingly, so that excessive pooling of a liquid cosmetic (2) in the brush portion (10) can be prevented.
