A method of manufacturing a semiconductor device is described. A board that includes a flat back face, corresponding to a resin sealing area, and a front face that has projections is provided. The projections are formed of a metal that is integral with the board and include (a) a bonding pad provided in an area surrounded by an area that contacts an upper die, (b) a wiring that is integrated with the bonding pad and which extends to a semiconductor element mounting area, and (c) an electrode provided in one body with the wiring. A semiconductor element is mounted on the semiconductor element area and electrically connected to the bonding pad. The board is placed on a lower die and resin is filled into a space formed by the board and upper die. The board is divided into multiple devices such that the projections are separated by removing the board exposed at the back face of the resin.
