Abstract:
There is provided an embossed film in which the frequency of loss of concavities is smaller, the embossed film including: a film main body; and a plurality of concavities formed on a surface of the film main body. A diameter of an opening surface of the concavity is larger than a visible light wavelength, an arrangement pattern of the concavities has periodicity along a length direction of the film main body, and the difference between the rate of loss of concavities in one end portion of the film main body and the rate of loss of concavities in the other end portion of the film main body is 10 ppm or less.
