TOOTH BRUSH

PROBLEM TO BE SOLVED: To provide a tooth brush which enhances the brushing effect on interdental parts and cervical parts and makes it possible to easily obtain the sufficient brushing effect on molars. SOLUTION: Many staples 12 of the tooth brush 10 formed by longitudinally and transversely planting many staples 12 bundled with bristles 11 to a flocking block 14 consist of front end side staple groups 12A existing on the front end side in the longitudinal direction X of the flocking block 14 and rear end side staple groups 12B existing on the rear end side in the longitudinal direction X. The front end side staple groups 12A are formed at the same height in the front end position of the tips of the adjacent staples in the direction perpendicular to the longitudinal direction X of the flocking block 14, and the rear end side staple groups 12B are so formed that the front end positions of the tips of their outer side staples 12b are higher than the front end positions of the tips of inner side staples 12b' and the front end positions of the tips of the staples 12a of the front end side staple groups 12A. The ratio of the planting length (m) of the front end side staple groups 12A to the planting length (n) of the many staples 12 in the longitudinal direction X of the flocking block 14 is 0.15 to 0.75.
