Abstract
A protective sheet for a solar battery module comprises a weather-resistant sheet (1) of, for example, a fluorocarbon resin, and a deposited inorganic oxide thin film (2) formed on one of the surfaces of the weather-resistant sheet (1). A surface-treated layer (3) is formed in the weather-resistant sheet (1) to enhance adhesion between the weather-resistant sheet (1) and the deposited inorganic oxide thin film (2).
