Patent ID: 8536457

Claim:
A wiring board comprising: a main substrate having a base material and a conductive pattern formed on the base material; a flex-rigid printed wiring board having an end portion positioned beside the main substrate and having a rigid substrate and a flexible substrate connected to each other, the end portion being connected to the rigid substrate by the flexible substrate, and the flex-rigid printed wiring board having a conductive pattern formed on a surface of the end portion of the flex-rigid printed wiring board; and an insulation layer formed over the conductive pattern of the main substrate and the conductive pattern of the flexible-rigid wiring board, the insulation layer having a plurality of via conductors formed through the insulation layer and a conductive pattern formed on the insulation layer and directly connecting the via conductors, wherein the plurality of via conductors includes a via conductor connected to the conductive pattern of the main substrate and a via conductor connected to the conductive pattern formed on the surface of the end portion of the flex-rigid printed wiring board such that the conductive pattern of the main substrate is electrically connected to the conductive pattern of the flex-rigid printed wiring board through the conductive pattern formed on the insulation layer.
