Electromagnetic wave shielding film

An electromagnetic wave shielding film comprising:

• an insulating protective layer;
• and
• a release film covering a surface of the insulating protective layer,
• wherein
• the release film has a transmittance of 20-80% at a wavelength of 535 nm, a tight attachment confirmability index Ia of 11 or more, the tight attachment confirmability index Ia being represented by expression 1, and a presence visibility index Iv of 11 or more, the presence visibility index Iv being represented by expression 2,
• Ia=(ΔL*12+Δa*12+Δb*12)0.5 (expression 1)
• Iv=(ΔL*22+Δa*22+Δb*22)0.5 (expression 2)
• where ΔL*1 represents a difference between the L* value of a surface of the release film before release and the L* value of the surface of the release film after release, Δa*1 represents a difference between the a* value of the surface of the release film before release and the a* value of the surface of the release film after release, and Δb*1 represents a difference between the b* value of the surface of the release film before release and the b* value of the surface of the release film after release, and ΔL*2 represents a difference between the L* value of the surface of the release film before release and the L* value of the surface of the insulating protective layer after release of the release film, Δa*2 represents a difference between the a* value of the surface of the release film before release and the a* value of the surface of the insulating protective layer after release of the release film, and Δb*2 represents a difference between the b* value of the surface of the release film before release and the b* value of the surface of the insulating protective layer after release of the release film, provided that the surface of the release film after release is opposite a surface of the release film that is attached to the insulating protective layer before release.
