A plurality of chip sealing bodies stacked on a wiring substrate with a connection terminal. The chip sealing body includes a semiconductor chip having a semiconductor integrated circuit, a pad and a conductive connecting material, and a resin sealing the semiconductor chip. The chip sealing body is shaped into a cubic form in which a portion of the conductive connecting material except an end portion located on an external device side and all surfaces of semiconductor chip is sealed by the resin and the end portion of the conductive connecting material located on the external device side is exposed from the cubic form. A conductive bonding wire connects the end portions of the conductive connecting materials and the connection terminal respectively. A resin sealing material seals the plurality of chip sealing bodies, the conductive bonding wire, and the wiring substrate.
