Patent ID: 8350388

Claim:
A component built-in wiring board, comprising: a first insulating layer; a second insulating layer positioned in a laminated state on the first insulating layer, the second insulating layer being a laminated layer of at least two insulating layers; a semiconductor element buried in the second insulating layer, having a semiconductor chip with terminal pads and having surface mounted terminals arrayed in a grid shape connected electrically with the terminal pads; an electric/electronic component further buried in the second insulating layer, having terminals on both sides thereof; a first wiring pattern sandwiched between the first insulating layer and the second insulating layer, including a first mounting land for the semiconductor element and a second mounting land for the electric/electronic component; a first connecting member connecting electrically the surface mounting terminal of the semiconductor element with the first mounting land; a second connecting member connecting electrically the terminals of the electric/electronic component with the second mounting land, made of a same material as a material of the first connecting member; a second wiring pattern sandwiched between the at least two insulating layers; and an interlayer connector sandwiched between a surface of the first wiring pattern and a surface of the second wiring pattern to penetrate partly through the second insulating layer in a layered direction, made of a conductive composition and having a shape with an axis corresponding to the layered direction and a diameter varying in an axial direction.
