Provided is a component-embedded board which includes: a first board including a first insulation layer, a first conductive layer formed on a second face of the first insulation layer, and an interlayer conductive portion penetrating the first insulation layer to be connected to the first conductive layer and protruding from a first face of the first insulation layer; an electric component connected to the interlayer conductive portion; and a second board including a second insulation layer having an opening portion incorporating the electric component, and a second conductive layer formed on at least either one of a first face and a second face of the second insulation layer. The second conductive layer includes a frame portion. The opening portion is formed so as to penetrate the second insulation layer in a thickness direction thereof over the entirety of the inner region of the frame portion.
