PROBLEM TO BE SOLVED: To enable to operate an optical semiconductor device normally and in a stable condition at all times by making the optical semiconductor device correctly inputting and outputting electrical signals. SOLUTION: A package for housing an optical semiconductor device comprises a substrate 1 having a placing part 1a on the top of which the optical semiconductor device 4 is placed through an electronic cooling device 5, a frame 2 having a through hole 2a and a notch 2b on its sides which is mounted on the substrate 1 in such a way that it surrounds the optical semiconductor device placing part 1a, a cylindrical fixing element 9 which is mounted in the through hole 2a or on the frame around the through hole 2a and to which an optical fiber element 11 is joined, a ceramic terminal 6 which is mounted on the notch 2b and on which a metallized wiring layer 8 is formed for electrically connecting electrodes of the optical semiconductor device 4 to an insulator 7, and a lid 3 which is mounted on the top of the frame 2 for hermetically sealing the optical semiconductor device 4. In this case, the insulator 7 of the ceramic terminal 6 is made of aluminum nitride sintered compact. |
