Abstract
A circuit board is provided with a metal plate, having openings, as core material. The opening gradually increases from a lower surface side toward an upper surface side of the metal plate. On both surface sides of the metal plate there are provided wiring patterns, respectively, via insulating layers. The insulating layer on an upper region of the opening and the corresponding wiring pattern are provided have a recess on the upper surface. To electrically connect each wiring pattern, the circuit board includes a conductor that penetrates the metal plate via the opening and which connects the wiring patterns with each other. An LSI chip is directly coupled to the upper surface side of the metal plate via a solder ball.
