Abstract

To improve heat dissipation efficiency in an electronic component embedded substrate for mounting an electronic component of a type being prohibited from connecting to a ground pattern. An electronic component embedded substrate includes an electronic component and a heat transfer block which are embedded in insulating layers, a wiring pattern facing a surface of the heat transfer block, a wiring pattern facing another surface of the heat transfer block, a via conductor connecting the wiring pattern and the surface of the heat transfer block, and another via conductor connecting the wiring pattern and the another surface of the heat transfer block. The surfaces are insulated from each other. Even when an electronic component of a type having large heat generation and being prohibited from connecting to a ground pattern is mounted, the wiring pattern functioning as a heat dissipation pattern is connected to a ground pattern on a motherboard.
