英语代词摘要：
PROBLEM TO BE SOLVED: To propo a method of manufacturing a resin sheet which allows through holes of various shapes including needle-like, conic or trapezoidal shapes to be pierced, and has fine holes which has little burrs and roundness or failure in shape on a bottom of the hole, is excellent in shape and dimensional accuracy, and has uniform aspects over a large area.
SOLUTION: The method of forming a fine through hole on a resin sheet includes steps of: supplying the resin sheet onto a heated stamper having fine protrusions; supplying a molten resin medium onto the resin sheet; pressurizing the softened resin sheet via the molten resin medium and piercing the resin sheet by the fine protrusions; cooling the molten resin medium and the resin sheet while pressurizing; peeling the solidified molten resin medium and the procesd resin sheet from the stamper; and peeling the procesd resin sheet from the solidified molten resin medium.
