Abstract
Provided is an electromagnetic wave shielding film capable of reducing a space formed between the electromagnetic wave shielding film and an electronic component on a wiring substrate and to increase an electromagnetic wave shielding effect. An electromagnetic wave shielding filmincludes a conductive layerhaving stretchability and a property of hardly returning to an original state thereof when once stretched, and an adhesion layerformed on one surface of the conductive layerand having insulating properties. The conductive layeris made of a conductive composition, including a resin having stretchability and a property of hardly returning to an original state thereof when once stretched and a conductive filler filled with the resin. The resin has a tensile permanent set of 2.5% or more and 90% or less.
