Abstract

The objective of the present invention is to provide a manufacturing method of a cylindrical case excellent in productivity without generating unnecessary places of a film part which is an insulating film and without requiring a stage that the film part which becomes a magnet part is mounted after punching stage, or the like. This method is a manufacturing method of the cylindrical case by which the cylindrical case 1 is punched by successively sending out a plate-shaped base stock 11 on which guide holes 12 are provided at a prescribed pitch along the longitudinal direction while being guided by these holes 12 with a progressive press device 8. A number of ring-like film parts 13 are formed on the plate-shaped base stock 11 on the basis of the guide holes 12. The cylindrical case 1 on the inner peripheral surface 5 of which the film part 13 is arranged is successively punched by performing the delivering stage of the plate-shaped base stock 11 with the progressive press device 8.
