摘要：

<P>PROBLEM TO BE SOLVED: To provide a toothbrush that can reduce, as the whole toothbrush, variation in the strength of bristles of the toothbrush having an angle-shaped brush part. <P>SOLUTION: The toothbrush 10 is designed to form a bristled surface 20 of a head part 12 in angle shape by connecting a first inclined surface 20a going up toward the tip, to a second inclined surface 20b going down toward the tip continuously with the first inclined surface 20a. Since the tips of a plurality of bristle tufts 22 bristled in the head part 12 are formed in angle shape along the continuation of the first inclined surface 20a and second inclined surface 20b, the difference of length between the long bristle tufts and short bristle tufts of the bristle tufts 22 bristled to form the brush part 14 in angle shape is reduced in comparison with the case of the head part 12 of not angle shape. Variation in the strength of the bristles 24 can thereby be reduced as the whole toothbrush 10. <P>COPYRIGHT: (C)2012,JPO&INPIT
