- 摘要：
To provide an interdental brush, which is easily inserted between teeth and can improve cleaning effect while giving a soft touch to the gum.
SOLUTION: Each filament 4 is inclined toward the base end of a brush part 2, with a filament tip position 4a being located closer to the base end of the brush part than a root position 4b ON the outer circumference of a core material in which the filament is planted. Particularly and the filament 4 is constituted in a curved shape in which the inclination to the base end of the brush part relative to a moving radius direction vertical to the axial line of the core material 3 is gradually increased from the root 4b to the tip 4a. The angle &beta of the line connecting the root 4b and the tip 4of a the filament 4 relative to the moving radius direction is set so that the average value of filaments 4 in a predetermined planting area ON the tip side of the brush part 2 is smaller than the average value of the filaments 4 in the remaining planting area ON the base end side. The filament length in the brush part 2 is set so that the filaments ON the base end side are long, compared with those ON the tip side and the brush part 2 has a conical outer circumferential shape.
