Electromagnetic wave shielding film

Provided is an electromagnetic wave shielding film which has sufficiently high bending resistance and sufficiently high electromagnetic wave shielding characteristics even when used in a transmission circuit for transmitting a signal in a high-frequency region. The electromagnetic wave shielding film according to the present invention comprises an adhesive layer, a shielding layer laminated on the adhesive layer, and an insulating layer laminated on the shielding layer, and is characterized in that: a plurality of openings having an opening area of 1-5000 [mu] m2 are formed in the shielding layer; the openings include first openings having an opening area of more than 1 [mu] m2 but not more than 300 [mu] m2 and second openings having an opening area of more than 300 [mu] m2 but not more than 5000 [mu] m2, the proportion (cumulative frequency) of the number of the first openings in the openings being 30-90%, and the proportion (cumulative frequency) of the number of the second openings being 10-70%. 本发明提供一种电磁波
