Electromagnetic shield film, flexible printed wiring board and their manufacturing methods

An aim of the invention is to provide an electromagnetic wave shield film capable of maintaining the electromagnetic wave noise shield effect, even if a metal thin film layer is cracked, and to provide a flexible printed wiring board with an electromagnetic wave shield film, and their manufacturing methods. An electromagnetic wave shield film 10 includes an insulating protective layer 12, a metalthin film layer 14 having a surface resistance of 0.01-0.3 [mu]m and an isotropic conductive adhesive layer 16 containing a conductive filler and having a surface resistance of 1-100 [mu]m in order. Aflexible printed wiring board with an electromagnetic wave shield film includes a flexible printed wiring board, an insulating film, and the electromagnetic wave shield film 10. 提供即使金属薄膜层中产生裂缝也能维持电磁波噪声的屏蔽效果的电磁波屏蔽膜及带有电磁波屏蔽膜的柔性印刷布线板及它们的制造方法。电磁波屏蔽膜(10)依次具有绝缘性保护层(12)、表面电阻为0.01Ω以上0.3Ω以下的金属薄膜层(14)、包含导电性填充剂且表面电阻为1Ω以上100Ω以下的各向同性导电性粘接剂层(16)，绝缘性保护层(12)由涂布包含热硬化性树脂和硬化剂的涂料并固化而形成的涂膜构成，厚度为1μm以上10μm以下，且在160℃的储存弹性率优选为5×10Pa以上1×10Pa以下。带有电磁
