摘要： PROBLEM TO BE SOLVED: To punch a hole even in a state of superposing a plurality of synthetic resin sheets, by preventing a hole part from becoming white, and preventing a projection from being formed in the hole part, even if a fine hole is formed in the transparent synthetic resin sheet.SOLUTION: A manufacturing device supports a load by a synthetic resin support part 23 in close contact with a base material sheet 13 by sandwiching the base material sheet 13 by opposing to a punching roller 22 when punching the hole by pressing the punching roller 22 having a plurality of punches 22a on an outer peripheral surface and rotating in the carrying direction of the base material sheet 13, to one surface of the base material sheet 13, by carrying the synthetic resin belt-like base material sheet 13 (an upper base material sheet 13a and a lower base material sheet 13b) along the longitudinal direction in a double-layered state.
