PROBLEM TO BE SOLVED: To provide a release multilayered film constituted so as to reduce the leaching amount of a film end surface incapable of being achieved in a conventional release multilayered film while keeping characteristics excellent in releasability, shape followability, uniform moldability, plating properties and appearance finish wrinkles of FPC. SOLUTION: In the release multilayered film having at least three layers, that is, a release side layer, an intermediate layer and a release opposite side layer, the resin of the release side layer and release opposite side layer comprises a polymethylpentene or a polymethylpentene/α-olefin copolymer and the resin of the intermediate layer has a melt flow rate of 0.2-3.0 g/10 min. A coverlay molding method using it is also disclosed. COPYRIGHT: (C)2005,JPO&NCIPI
