<P>PROBLEM TO BE SOLVED: To provide a laminate having high thermal conductivity of an insulating layer and high adhesion between the insulating layer and an electric conductive layer. <P>SOLUTION: The laminate 1 includes a thermal conductor 2 with thermal conductivity of 10 W/m.k or more, and first and second insulating layers 3 and 4. The first and second insulating layers 3 and 4 are formed by using the same curable composition. The first and second insulating layers 3 and 4 contain an inorganic filler with the thermal conductivity of 10 W/m.k or more, respectively. The curing rate of the first insulating layer 3 is 50% or more, and the curing rate of the second insulating layer 4 is less than 80%. The curable composition contains a liquid epoxy compound with viscosity at 25°C of 15,000 mPa s or less, or a crystalline epoxy compound with a melting point lower than 140°C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
