A combination substrate includes a first substrate having multiple wiring board mounting pads for installing a printed wiring board and multiple connection pads on the opposite side of the wiring board mounting pads, a second substrate having multiple package substrate mounting pads for loading one or more package substrates and multiple connection pads on the opposite side of the package substrate mounting pads, a resin component filling a space between the first substrate and the second substrate, and multiple component loading pads positioned to load an electronic component between the first substrate and the second substrate and formed on one of the first substrate and the second substrate. The connection pads of the second substrate are electrically connected to the connection pads of the first substrate. |
