PROBLEM TO BE SOLVED: To relieve a metallic sense of discomfort felt when an interdental brush is obliquely inserted into an interdental space. SOLUTION: The interdental brush 10 includes: a grip part having a linearly extending front grip part and a rear grip part integrally formed in one end of the front grip part; and a wire brush part having a wire part extending on the center line from the other end of the rear grip part and a brush part made of a plurality of filaments planted along the center line of the wire part. The wire brush part has an end filament group extending from the end to the proximal end side, and a proximal end filament group continued from the end filament group and extending to the proximal end side. The density of the filaments planted in the wire part in the end filament group is higher than in the proximal end filament group. COPYRIGHT: (C)2010,JPO&INPIT
