PROBLEM TO BE SOLVED: To provide a toothbrush by which bristle bundles hit a tooth surface by an approximately uniform pressure even if the tooth surface has unevenness or a sharp slope, and which can surely remove dental plaque and so forth. SOLUTION: This toothbrush has a movable section (6) including a transplantation face on which bristle tufts are transplanted, and a supporting section (4) which includes a handle section (2) and supports the movable section. Then, the movable section (6) is tiltably supported by the supporting section (4) through a resilient member (12) to form a bristle transplanted body. COPYRIGHT: (C)2005,JPO&NCIPI
