摘要

The composite circuit board comprises a substrate (13) made of an insulating material, a thick circuit conductor (11), embedded in this substrate (13), which includes a parts-mounting section (11a) and has a predetermined circuit pattern, a thin circuit conductor (12), provided on the surface of said substrate (13), which includes a land (12a) corresponding to the parts-mounting section (11a) of said thick circuit conductor (11) and has a predetermined circuit pattern, and a conductor means (14, 14a) for electrically connecting said land and said parts-mounting section. In this circuit board, the land (12a) and the part-mounting section (11a) are connected by a conducting member provided in this through hole (14).
