A printed wiring board is provided with a base material, which has at least one wiring and is composed of an adhesive insulating base material and a conductive layer formed on one plane of the insulating base material; a penetrating electrode which is connected to the conductive layer, penetrates the insulating base material and is composed of a conductive paste; and an IC chip having a rewiring section. An IC chip is embedded in an interlayer adhesive material of the base material having the wiring, by connecting the rewiring section with the penetrating electrode. A supporting substrate is arranged on a plane opposite to the rewiring section of the IC chip through the adhesive layer, and the rewiring section and the base material having the wiring constitute a rewiring layer. Therefore, the multilayer printed wiring board having fine components mounted thereon is provided by simple process without increasing the cost and deteriorating the yield. |
