NOVELTY - The sheet (1) has a heat dissipation film (2), and an adhesive compound layer (3) that is laminated on one face side of a substrate layer (4) of the heat dissipation film. A fine bumpy portion (8) is formed on the entire surface of the heat dissipation film. The heat dissipation film has a heat dissipation layer (5) that is laminated on other face side of the substrate layer. The heat dissipation layer is made of binder (7) and fine particles (6) selected from metal beads and inorganic oxide beads. The adhesive compound layer is covered by a release sheet.    USE - Heat dissipation sheet for back face of solar battery module (claimed).    ADVANTAGE - Since the adhesive compound layer is laminated on one face of the substrate layer, the heat dissipation property of the solar battery module can be improved reliably. The efficiency of electric power generation of the solar battery module can be enhanced effectively. The useful life of the solar battery module can be extended efficiently. The handleability of the heat dissipation sheet can be improved reliably, and the heat dissipation sheet can be sealed and protected effectively. The generation of defects such as scratches in the heat dissipation film can be prevented reliably, and the deterioration of the gas barrier properties can be suppressed efficiently. The aged deterioration of the heat dissipation layer can be inhibited effectively. The contact of the adhesive compound layer with other substance can be prevented reliably by using a release sheet. The workability of the solar battery module can be increased efficiently.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for solar battery module.
