PROBLEM TO BE SOLVED: To provide: an article with a low-reflection film which exhibits a low reflectance of light incident thereon at a large incident angle and has good abrasion resistance; and a solar battery module which achieves high power generation efficiency even if it is installed so that an angle formed by the surface of the solar battery module and a horizontal plane is 50-90 degrees.SOLUTION: The article 1 with a low-reflection film comprises: a transparent base material 10; and a low-reflection film 12 provided on the transparent base material 10. The low-reflection film 12 includes three layers consisting of a lower layer 14, an intermediate layer 16 and an upper layer 18. The average reflectance of light of wavelengths of 400-1200 nm incident on the surface of the low-reflection film 12 at an incident angle of 70 degrees is 7% or less. The average reflectance of light of wavelengths of 600-900 nm incident on the surface of the low-reflection film 12 at the incident angle of 70 degrees is 5% or less. The average reflectance of light of wavelengths of 400-1200 nm incident on the surface of the low-reflection film 12 at the incident angle of 60 degrees is 3% or less. The average reflectance of light of wavelengths of 400-1200 nm incident on the surface of the low-reflection film 12 at the incident angle of 50 degrees is 2% or less.
