Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a substrate module for mounting a heat generator that can improve a heat release characteristic with a simple structure and that can exhibit an excellent heat release characteristic even in the use for a narrow and long illumination device such as a fluorescent tube, and provide an illumination device with the substrate module for mounting a heat generator.SOLUTION: A substrate module 1 for mounting a heat generator is formed by attaching to a metal plate 10 a flexible printed wiring board 20 for mounting a heat generator 30. The flexible printed wiring board 20 has a larger area than the metal plate 10, and has a conduction layer 22 on its surface. The flexible printed wiring board 20 is attached to the metal plate 10 by being bent from one surface side to the other surface side of the metal plate 10, so that the board 20 is in contact with the one surface side and the other surface side.
