NOVELTY - A base portion (1) having mounting regions (5) and lead electrodes (6) are prepared (a). A support (2) is composed of thermosetting resin, and is surrounded each of the mounting regions of base portion. Solar cells (3) are mounted on the mounting regions. Condensing lens (4) is molded above mounting regions, in order to encapsulate solar cells. The surface of mounting regions of prepared base portion is plated, and the support is joined to base portion, to obtain concentrating solar cell module (10). In molding process, the condensing lens is molded mounting regions.    USE - Production of concentrating solar cell module for power generation.    ADVANTAGE - The method is economical, and enables manufacture of durable concentrating solar cell module with improved heat dissipation property and photoelectric conversion efficiency, due to support with high reflectivity and strength.    DETAILED DESCRIPTION - A base portion having mounting regions for mounting solar cells and lead electrodes for electrically connecting the solar cells with external electrodes are prepared (a). A support is composed of thermosetting resin, and is surrounded each of the mounting regions of base portion. The solar cells are mounted on the mounting regions. A condensing lens is molded above the mounting regions, in order to encapsulate the solar cells. The surface of the mounting regions of the prepared base portion is plated after the preparation process (a) and before mounting process. The support is joined to the base portion after the mounting process and before the molding process, to obtain concentrating solar cell module. In molding process, the condensing lens is molded with transparent thermosetting silicone resin.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic sectional view of the concentrating solar cell module.
