PROBLEM TO BE SOLVED: To provide a fixing structure capable of mounting even a cylindrical optical component which is weak against heat or external force on a substrate, without increasing production time and production cost.SOLUTION: A positioning mechanism (holding metal fittings 4) for positioning one or more cylindrical optical component bodies 101 to a substrate 3, and hyperviscosity silicon based adhesive 5 to be applied between the positioning mechanism (holding metal fittings 4) and the cylindrical optical component body 101 are provided. The viscosity of the silicon based adhesive 5 is 50 Pa s or higher. |
