COIL SHEET PRODUCTION METHOD, AND COIL PRODUCTION METHOD

摘要

The main purpose of the present invention is to provide: a coil sheet production method which is capable of inhibiting a reduction in the peeling properties between a base layer and an adhesive layer; and a coil production method. This coil sheet (37) production method includes: a first cutting step in which an initial sheet (37a) having, sequentially stacked therein, a conductor layer (32), a heat-resistant insulation layer (33), an uncured heat-curable adhesive layer (34), and a base layer (35) is employed, and etching is used to cut the conductor layer (32) into a prescribed shape; and a second cutting step which is performed after the first cutting step, and in which etching is used to cut the insulation layer (33) and the adhesive layer (34) into prescribed shapes.
