Wiring board and method for manufacturing the same

摘要

A wiring board including a first rigid wiring board having an accommodation portion and a conductor, a second rigid wiring board accommodated in the accommodation portion of the first rigid wiring board and having a conductor electrically connected to the conductor of the first rigid wiring board, and an insulation layer formed on the first rigid wiring board and the second rigid wiring board. The accommodation portion of the first rigid wiring board has wall surfaces tapering from a first surface of the first rigid wiring board to a second surface on the opposite side of the first surface, and the second rigid wiring board has side surfaces tapering such that the side surfaces of the second rigid wiring board substantially fit into the wall surfaces of the accommodation portion of the first rigid wiring board.
