Patent ID: 8779299

Claim:
An electronic component-embedded board, comprising: a substrate; the electronic component having terminals and mounted on the substrate; an insulating layer formed so as to cover the electronic component; and a wiring layer electrically connected to the terminals of the electronic component, wherein each of the terminals of the electronic component has a plurality of metal layers, the plurality of metal layers include at least two layers of an outermost surface layer and a connection layer positioned on a lower layer side than the outermost surface layer, the outermost surface layer has a higher electric resistance than the connection layer or the wiring layer, the outermost surface layer is formed in a portion which comes in contact with the insulating layer, the insulating layer is directly bonded to the outermost surface layer, the outermost surface layer is not formed in a portion which comes in contact with the wiring layer, and the wiring layer is electrically connected to the connection layer via no outermost surface layer.
