PURPOSE:To obtain the subject prepreg for electronic equipment, etc., sufficiently workable at low temperature under low pressure in bonding and capable of shortening the working time by successively applying a tetrafluoroethylene- hexafluoropropylene copolymer layer, etc., on a cloth substrate. CONSTITUTION:The objective prepreg 7 is produced by forming a layer 2 of a tetrafluoroethylene-hexafluoropropylene copolymer (abbreviated to FEP) or a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer on a cloth substrate 1 and applying a polytetrafluoroethylene layer 3 and an FEP layer 4 on the copolymer layer 2. |
