PROBLEM TO BE SOLVED: To provide a production method of an electromagnetic wave shielding film in which excellent durability is ensured by enhancing adhesion between respective layers composing the shielding film, and efficiency of a production process can be enhanced, and to provide an electromagnetic wave shielding film produced by the method.SOLUTION: An electromagnetic wave shielding film is produced by a method including: an insulation layer formation step for forming an insulation layer 20 on a first release film 11; a metal patterning step for printing a metal pattern 30 on the insulation layer; a conductive adhesive layer formation step for forming a conductive adhesive layer 40 on a second release film 12; and a release film combination step for forming an electromagnetic wave shielding film by combining the first and second release films so that the metal pattern and the conductive adhesive layer come into contact with each other.SELECTED DRAWING: Figure 2 【課題】構成する各層の間の付着力が向上して耐久性に優れ、製造工程の効率を上げることができる電磁波遮蔽フィルムの製造方法及びこれから製造された電磁波遮蔽フィルムを提供する。【解決手段】第１離型フィルム１１上に絶縁層２０を形成する絶縁層形成段階と、前記絶縁層上に金属パターン３０を印刷する金属パターン形成段階と、第２離型フィルム１２上に導電性接着剤層４０を形成する導電性接着剤層形成段階及び前記金属パターンと前記導電性接着剤層が当接するように第１離型フィルム及び第２離型フィルムを合紙して電磁波遮蔽フィルムを形成する離型フィルム合紙段階を含んで製造される。【選択図】図２
