Abstract

Disclosed herein is an IC embedded substrate that includes a core substrate having an opening, an IC chip provided in the opening, a lower insulating layer, and upper insulating layer. The IC chip and the core substrate is sandwiched between the lower insulating layer and the upper insulating layer. The upper insulating layer is formed in such a way as to fill a gap between a side surface of the IC chip and an inner peripheral surface of the opening of the core substrate. A first distance from the upper surface of the IC chip to an upper surface of the upper insulating layer is shorter than a second distance from the upper surface of the core substrate to the upper surface of the upper insulating layer.
