摘要:
The present invention provides a wiring board giving good heat dissipation over a long period of use. The present invention also provides a method for producing a wiring board, including coating a surface of a metal substrate 2, which is made of an aluminium plate, with a composition 3 containing a substance having a polysiloxane structure and inorganic particles having insulating and heat-dissipating properties ( Fig. 1(B) ), curing the composition 3, then bonding a copper foil 4 to the cured composition 3A ( Fig. 1(C) ), and partially removing the copper foil 4, thereby forming a wiring layer 5 ( Fig. 1(D) ).
