In order to enhance the power generation efficiency of a solar battery, the solar battery is formed to have a configuration in which a sealing material sheet formed of a sealing material having a wavelength conversion material mixed therein and having a thickness (c) is disposed between a front glass having an antireflection film and a solar battery cell; the wavelength conversion material is a needle fluorescent substance capable of converting short-wavelength light to long-wavelength light; and when a long diameter and a short diameter of the needle fluorescent substance are defined as “a” and “b”, respectively, there are relations of “a>b” and “a>c”. According to this, more outgoing light from the fluorescent substance can be directed toward the side of the solar battery cell, so that the power generation efficiency can be enhanced.
