Abstract
In a wiring base body of a printed wiring board, a conductive post including a wiring portion and a wiring are embedded in an insulating resin film. Therefore, even in a region in which a wiring portion is formed, the wiring base body is not increased in thickness. In addition, even in a region in which a wiring is formed, the wiring base body is not increased in thickness. Therefore, it is possible to obtain a printed wiring board having high flatness by stacking a plurality of wiring base bodies and constituting a printed wiring board.
