Zusammenfassung:	PURPOSE:To drill an arbitrary shaped hole efficiently and with high precision by forming a through-hole and polishing the nonthrough-hole surface side of a belt having the nonthrough-hole drilled. CONSTITUTION:In order to carry out the drilling at the toothed part of a toothed belt which is continuously shaped, a pin 13 having the height smaller than the total thickness of the belt is installed at the toothed bottom part 12 of a shaped wheel 11, and a drilled toothed belt 14 is shaped. Then, a prescribed H type drilled belt 16 is obtained by polishing the belt transfer face part 15. Polishing is carried out generally by using a grinder, and the polishing portion is kept in about 0.5-1.0mm or so, and it is enough not to particularly carry out the surface treatment for the polished surface. Accordingly, in comparison with the case using a cutter or a blanking mold, an arbitrary shaped hole can be drilled with high precision.
