Abstract
A circuit board includes a wiring board which includes an insulative board having a wiring pattern on one surface thereof, a connection hole being formed in the insulative board such that the connection hole reaches the wiring pattern, a conductive bump, which is formed by growing a plating on the wiring pattern, being embedded in the connection hole, and the conductive bump serves as a connection to a wiring pattern which is intimately attached to the other surface of the insulative board.
