  • Patent number: 11812543
    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 film 1 includes a conductive layer 3 having stretchability and a property of hardly returning to an original state thereof when once stretched, and an adhesion layer 4 formed on one surface of the conductive layer 3 and having insulating properties. The conductive layer 3 is 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.
