A semiconductor package includes a print circuit part, a lower chip, an upper chip, a thermal conductivity part, and an encapsulation resin. The lower chip and the upper chip are mounted on the print circuit part through wire bonding connection. The thermal conductivity part efficiently dissipates heat from the chips to the outside of the package. The encapsulation resin entirely seals the package while exposing the thermal conductivity part. A adhesive sheet is hardened to form a bonding layer between the thermal conductivity part and the upper chip, a bonding layer between the semiconductor chips, and a bonding layer between the semiconductor chip and the wired component. The configuration contributes to miniaturization, high integration, and heat resistance reduction of a semiconductor package using high-heat-generating ICs.
