PROBLEM TO BE SOLVED: To eliminate generation of local and small bendings of the radius of curvature in lead fiber between optical parts accommodated in a package and a sealing part due to temperature change, and to prevent deterioration of transmission characteristic due to bend. SOLUTION: Optical components assembly is composed of optical parts 1, having the lead fiber 2 and packages 3, 6 accommodating the optical parts 1. The lead fiber 2 of the optical parts 1 is led out outside from efferent ports 4, 7, provided in a wall surface of the packages 3, 6 and a direction, where the lead fiber 2 is led out from the optical parts 1 and a direction, where the lead fiber 2 is led out from the efferent ports 4, 7 of the packages 3, 6 have an inclination. Space between inwall surfaces of the efferent ports 4, 7 and the lead fiber 2 to be inserted therein is sealed airtightly, and the lead fiber 2 between the optical parts 1 and the part sealed airtightly is not fixed to the inwall surfaces of the packages 3, 6 and is accommodated in a bent state.
