An electromagnetic wave shielding sheet according to the disclosure is configured by a protection layer, a metal layer, and a conductive adhesive layer. The metal layer has a plurality of openings, and an aperture ratio of the opening is 0.1%-20%. In addition, a tensile breaking strength of the electromagnetic wave shielding sheet is 10 N/20 mm-80 N/20 mm.

An electromagnetic-wave shielding sheet is an electromagnetic-wave shielding sheet used to form an electronic component-mounted substrate, the electronic component-mounted substrate including an electromagnetic-wave shielding layer covering at least a part of a step part and an exposed surface of a substrate, in which the electromagnetic-wave shielding sheet is a laminate including a cushion layer and a conductive layer, the conductive layer is an isotropic conductive layer containing a binder resin and a conductive filler, a thickness of the conductive layer is 8 to 70 &#x3bc;m, and a content of the conductive filler in a region on a side opposite to a cushion layer side in the conductive layer is larger than that in a region on the cushion layer side in the conductive layer.
