<P>PROBLEM TO BE SOLVED: To provide an LED mounting substrate which reduces the cost of an LED module. <P>SOLUTION: An LED mounting substrate 10 is formed extending in one direction, and multiple LEDs 2 are mounted on the LED mounting substrate 10 so as to be arranged parallel to each other in the one direction. In the LED mounting substrate 10, a base material 13 made of polyimide, wiring layers 15 disposed directly on one surface of the base material 13 and formed by copper foil, and a heat radiation layer 14 disposed directly on the other surface of the base material 13 and formed by metal foil are laminated to be formed into a flexible film shape. <P>COPYRIGHT: (C)2013,JPO&INPIT |
