PROBLEM TO BE SOLVED: To provide a small-sized optical semiconductor element carrier and its mounting structure which is suitable to the highly accurate mounting of such an optical semiconductor element as a surface-received light-emitting semiconductor element and is excellent in its productivity and its high-frequency characteristic. SOLUTION: In an optical semiconductor element carrier C comprising an optical semiconductor element 2 mounted on a base 1 made of single-crystal silicon, the base 1 has an optical semiconductor element mounting surface comprising [110] plane or [100] plane, whereon the optical semiconductor element 2 is mounted and has at least two inclined surfaces A2, A3 comprising [111] plane which are positioned on the rear-surface side of the base 1 in the case of the standing of the base 1. |
