摘要： A semiconductor element 22 is mounted on a stem 24 where a flat surface serving as the mounting part of the semiconductor element 22 is provided on a part of a cylindrical part, and the stem 24 is inserted and hermetically sealed into a cap 25 such that the cylindrical part comes into contact with the cap 25. The size of the cylindrical shape of the stem 24 is minimized as a width of the mounting part so large as to mount the semiconductor element 22. Thus it is possible to achieve high heat dissipation and reduce the thickness of a semiconductor device 100, and further reduce the sizes of an optical pickup device and an optical disk drive unit.
