Abstract: In order to eliminate non-uniformity in the appearance of a cover glass for photoelectric conversion devices, the reflectance curve of the cover glass is extremely flattened. Provided is a cover glass for photoelectric conversion devices that includes a glass sheet having an uneven surface such as a figured glass, and a reflection-reducing film formed on the uneven surface. The reflection-reducing film includes silica fine particles and a binder for the silica fine particles. The silica fine particles are arranged in a single layer on the top portion of the uneven surface of the glass sheet, while the silica fine particles are arranged in stacks to a thickness equivalent to at least three layers on the bottom portion of the uneven surface. The uneven surface of the glass sheet has an average spacing Sm of at least 0.4 mm but not more than 2.5 mm and an arithmetic average roughness Ra of 0.5 ?m to 5 ?m. The cover glass has a reflectance of at least 1.
