PROBLEM TO BE SOLVED: To provide a brush which has long life because a bristle end can be extended according to ablation of the bristle end and which can polish narrow details because it has a stick-like elongated shape by solving a problem that conventional brushes become unusable when their bristle ends are abraded and the bristle ends hardly reach a portion to be polished and it is hard to effectively polish the narrow details because the brush is wide. SOLUTION: A hair portion 1 is made by passing a twisted yarn portion 4 through an outer pipe 2 which is a gripping portion and pushing out one end of the twisted yarn as the hair portion. A stopper portion 3 is used to prevent the twisted yarn from tottering and an end portion 5 is used to the twisted yarn or the like from loosening, a portion of the twisted yarn longer than the outer pipe can be used as the bristle end. The brush is elongate because it has a stick-like shape. Thus, the brush has long life and can polish the narrow details. COPYRIGHT: (C)2006,JPO&NCIPI
