Abstract
An electromagnetic wave shielding film has permeability to volatile components, shielding characteristics, and resistance to folding. The electromagnetic wave shielding film includes an adhesive layer; a metal layer made of a metal and placed on the adhesive layer; and an insulating layer placed on the metal layer. Multiple openings are formed in the metal layer; the openings include openings (A) including island-shaped metal layer fragments, each opening (A) having island-shaped metal layer fragments formed therein, and the openings (A) including island-shaped metal layer fragments include openings (A) including one or more island-shaped metal layer fragments. Each opening (A) defines an opening (A) including island-shaped metal layer fragments in which a total area of the island-shaped metal layer fragments accounts for 40 to 80% of an area inside a contour of the opening (A).
