PROBLEM TO BE SOLVED: To enhance the optical property of an LED-mounted module having a reflective material and the productivity thereof.SOLUTION: In a substrate 1 for LED devices, a reflective material 15 is a monolayer resin film arranged by molding a reflective material composition including a polyethylene-based resin of 0.870-0.940 g/cmin density as a base resin, and a white pigment, or a multilayer resin film including, as an outermost layer, a contact-reinforcement layer arranged by molding the reflective material composition. The reflective material has through-holes 151 for LED device mount, and a Young's modulus of 1.0E+4 to 1.0E+6 Pa at 160°C.SELECTED DRAWING: Figure 3 |
