Memory card and method for manufacturing the same
A memory card includes a circuit board, semiconductor chips mounted on different areas on the circuit board, a semiconductor chip with a semiconductor electrode on its top face and being fixed such that at least a part of its bottom face faces at least a part of a top face of the semiconductor chip, a wire for connecting the semiconductor electrode and a board electrode on the circuit board to achieve a mounting state of the semiconductor chip, and a cover for covering a circuit formation area from an upper side of the circuit board. The circuit formation area includes three semiconductor chips and the wire. At least a part of each of three semiconductor chips, at least a part of the circuit board, and the wire are covered with secondary sealing resin and primary sealing resin.
