Abstract

A toothbrush is provided that can sufficiently ensure a fixing force of a bristle bundle by a flat wire while suppressing the occurrence of cracking or whitening in a head portion, even when the head portion is thin-walled, has a good operability in an oral cavity, and has a large-diameter bristle bundle having an effect of improving a feeling of massage. A toothbrush (1) includes a handle body (1a) made of resin including a head portion (10) and adopts a flat wire type bristle implanting, wherein a thickness of a head portion (10) is 2 mm or more and 4 mm or less, a ratio of first bristle implantation holes (11a) having a diameter of 1.8 mm or more is 10% or more, two or more first bristle implantation holes (11a) are arranged in a long axis direction of the handle body (1a), and at least one set of the first bristle implantation holes (11a) adjacent to each other in the long axis direction satisfies a condition that a ratio of a stress generation parameter P1 to a long axis stress relaxation parameter P2 is 20 to 30%.
