Abstract
An electromagnetic shielding sheet of the present invention includes a transparent base sheet and a metal layer attached to one surface of the transparent base sheet. The metal layer has a mesh part, a peripheral mesh part surrounding the mesh part, and a grounding frame surrounding the peripheral mesh part. A width of lines forming meshes in the peripheral mesh part gradually increases from the mesh part toward the grounding frame. The lines of the electromagnetic shielding sheet are scarcely bent or broken in all processes including fabricating and assembling processes, and the electromagnetic shielding sheet is excellent in handling ease.
