Patent ID: 8633397

Claim:
An electronic device embedded printed circuit board, comprising: a core substrate; a first inner circuit formed on one surface of the core substrate, wherein a first area is demarcated on one surface of the core substrate by the first inner circuit; a second inner circuit formed on an other surface of the core substrate, wherein a second area is demarcated on the other surface of the core substrate by the second inner circuit and the second area is wider than the first area; a cavity formed to penetrate the core substrate on the basis of the first inner circuit, wherein a shape and a size of a transverse section of the cavity are the same as the first area, an upper area of the cavity has a same position as the first area and a lower area of the cavity is positioned inside the second area; an electronic device being embedded in the cavity, an electrode being formed on a surface of the electronic device; a first insulation layer being stacked on the one surface of the core substrate; and a second insulation layer being stacked on the other surface of the core substrate, the second insulation layer having a same thickness as the first insulation layer, wherein the second inner circuit is separated from an inner wall of the cavity in an outward direction.
