ABSTRACT:
The circuit board for mounting semiconductor elements comprises a core substrate10formed of a fiber reinforced metal, an insulating layer14formed on the core substrate10, and an interconnection layer20formed on the insulating layer14, whereby the circuit board for mounting semiconductor elements can have a thermal expansion coefficient approximate to that of silicon, and light and thin but has high rigidity.
