To cut down with cost through miniaturization of a device and simplification of manufacturing process by reducing the number of parts.
The light-emitting module using solar energy generation has a solar battery module 1, a light-emitting module 9 and a group of electronic circuits for having the modules emit light integrally mounted on one board. The solar battery module 1 is set on the surface of the board and a light- emitting module made of one or a plurality of light-emitting element and a group of electronic circuits 4 to 8 for having the light-emitting module emit light are set on the rear surface of the board. The solar battery module 1, the light-emitting module and the group of electronic circuits 4 to 8 are connected through a through-hole IC fitted on the board 2. Or, another way is to arrange the light-emitting module on the surface of the board 2.
