Electronic component embedded substrate
An electronic component embedded substrate includes: a substrate that includes an insulating layer and has a first principal surface and a second principal surface; an electronic component that is embedded in the substrate and has at least one first terminal, at least one second terminal, and a capacity part; at least one via conductor that are formed in the insulating layer and electrically connected to the second terminal; and an adhesion layer that is in contact with the second terminal on an end face of the second terminal which are close to the second principal surface. The electronic component is laminated with the insulating layer, and adhesion strength between the adhesion layer and the insulating layer is higher than that between the second terminal and the insulating layer.
