Electronic component built-in substrate and method of manufacturing the same

摘要

A first wiring substrate has a first wiring substrate main body and a first wiring pattern provided on a first surface of the first wiring substrate main body. A first electronic component is surface-mounted on the first wiring pattern. A second wiring substrate has a second wiring substrate main body and a second wiring pattern provided on a first surface of the second wiring substrate main body. The second wiring substrate is arranged under the first wiring substrate such that the first surface of the first wiring substrate main body opposes to the first surface of the second wiring substrate main body. A second electronic component is surface-mounted on the second wiring pattern, and arranged to oppose to the first electronic component. A resin member seals a space between the first wiring substrate and the second wiring substrate.
