CONSTITUTION: The toothbrush 1 consists of a brush part 3 formed by providing vertically bristles 2 and a grip part 4, and at least these bristles 2 are covered with a rubber layer 5. In this case, it is allowable that the brush part 3 formed by providing vertically the bristles 2 and the grip part 4 are formed integrally, or it is also allowable that both the parts are constituted of separate bodies, and formed so that this brush part 3 can be attached to the tip part of the grip part 4 so as to be freely attachable and detachable. Even if the bristles 2 start to be bent or opened by using the brush 1, the bristles 2 are returned to its original state by elastic restoring force of this rubber layer 5, and as a result, bending and opening of the bristles 2 are suppressed to the utmost. As a result, the toothbrush 1 can be used extending over a long period, and also, stimulation to gums becomes as small as possible by this rubber layer 5.
