摘要： This method of manufacturing a brush 1 comprises: a first step of forming a support body 10 in which through holes 14 are formed; and a second step of inserting a brush bristle 20 in a bent state into each through hole 14 from one side of the through hole 14 to cause a looped bristle to project from the through hole 14 on the other side.
