| description | The present invention relates to an electromagnetic wave shielding film, a flexible printed wiring board, and a method of manufacturing the same. In particular, the electromagnetic wave shielding film, the flexible printed wiring board, and the method of manufacturing the same, by which the electromagnetic wave noise shield effect can be maintained even a metal film layer has a crack. The electromagnetic wave shielding film (10) has an insulating protective layer (12), an electromagnetic wave shielding layer, a metal thin film layer (14) having a surface resistance of 0.01 ohm or more and 0.3ohm or less, an isotropic conductive adhesive layer (16) which contains a conductive filler and has the surface resistance of 1 ohm or more and 100 ohm or less, wherein the increase in electric resistance of the electromagnetic wave shielding layer due to cracks in the metal thin film layer is suppressed by 10 times or less.
