PROBLEM TO BE SOLVED: To provide a photovoltaic device capable of achieving both the effect of preventing the reflection of light and reliability at a high level.SOLUTION: A photovoltaic device 10 includes: a glass substrate 12; an antireflection layer 14 formed on the light receiving surface side of the glass substrate 12; and a photovoltaic element 16 provided on a side opposite to the light receiving surface of the glass substrate and converting light into electricity. The antireflection layer 14 is configured to have a refractive index lower than that of the glass substrate 12, and the glass substrate 12 has irregularities having a root-mean-square roughness RMS of within the range of 100-1,100 nm on the light receiving surface side 12a. |
