This invention provides a solar battery module having long-term durability at low cost. The CIS-type thin-film solar battery module (1) comprises a glass substrate (2A), a CIS-type thin-film solar battery circuit (2) provided on the glass substrate (2A), and a cover glass (4) formed of, for example, an inexpensive and durable white-plate semi-reinforced glass and applied to the CIS-type thin-film solar battery circuit (2). The adhesive is in a heat crosslinked ethylene-vinyl acetate (hereinafter referred to as "EVA") resin film (3) (or sheet). When an EVA resin film (3) is used, the amount of the EVA resin used is reduced. In the crosslinking, gas generated from an EVA resin film is absorbed by vacuum suction to prevent the occurrence of bubbles and the like. A large-capacitance electric storage device (9) is provided on the glass substrate on its side remote from a circuit installation face, and photovoltaic power thereof is stored. |
