There is disclosed a resin-sealed semiconductor device in which plural terminal portions each integrally having an inner terminal on a surface and an outer terminal on a rear face are arranged two-dimensionally substantially in a plane electrically independent of one another. A die pad is electrically independently disposed in a substantially middle portion in the plane where the terminal portions are arranged two-dimensionally. A semiconductor element is mounted on the die pad. The inner terminals of the terminal portions are electrically connected via wires to terminals of the semiconductor element, and the entirety is sealed with a resin in such a manner that the outer terminals of the terminal portions are partially exposed to the outside. Therefore, an occupancy ratio of the semiconductor element in the semiconductor device is increased. The semiconductor device can be miniaturized. The mounting density onto a circuit substrate can be enhanced. Also, by forming outer electrodes on the outer terminals, different from the conventional TSOP or another small-sized semiconductor device, multiple pins can be easily provided.
