Light extraction film for EL elements, surface light emitting body, and method for producing light extraction film for EL elements

To provide: a light extraction film for EL elements, which enables a surface light emitting body to have a good balance between suppression of emission angle dependence of the wavelength of emitted light and improvement of light extraction efficiency and luminance in the normal direction; and a surface light emitting body which has improved light extraction efficiency and luminance in the normal direction, while being suppressed in emission angle dependence of the wavelength of emitted light. [Solution] A light extraction film (10) for EL elements, which comprises a recessed and projected structure (12). The recessed and projected structure (12) is provided with a plurality of spherical projections (15), each of which contains a resin and fine particles (16) added into the resin. The content of the fine particles (16) in the spherical projections (15) is 22-55% by mass, and the average maximum diameter (A ave ) of the bottom portions of the spherical projections (15) and the volume average particle diameter (P) of the fine particles (16) satisfy the following mathematical formula (1).
