(EN) Provided is a light-diffusing film for LED lamps that achieves both high concealability and light-use efficiency. The light-diffusing film for LED lamps includes: a single sheet of substrate,an internal scattering layer,and a surface shaping layer. The internal scattering layer contains a binder and particles. The average particle size (A) of the particles is from 0.5 [mu]m to 5.0 [mu]m. The difference in refractive index between the particles and the binder is from 0 to 0.15. The amount of said particles contained in 100 parts by mass of said binder is from 10 parts by mass to 120 parts by mass.
