PROBLEM TO BE SOLVED: To provide an optical data link which thermally connects a data link housing and the body part of an optical subassembly (OSA) while absorbing the variation in the relative positions of the data link housing and the body part of OSA without using a thick heat conduction sheet. SOLUTION: The optical data link includes, in the housing: a transmitting optical subassembly (TOSA) 4 which incudes a photoelectric conversion element in the body part 4a and has a sleeve 4b in which the ferrule of an optical connector is inserted; and a circuit substrate 6 (7) electrically connected to the TOSA 4. The optical data link further includes: a metal member 9 which is fitted while the inner face thereof is made contact to the heat radiation face of the body part 4a of TOSA 4 to conduct the heat generated in the body part 4a of the TOSA 4 to the housing and radiate the heat outside; and a holding member 8 which holds the TOSA 4 which is made contact to the outer face of the metal member 9 and holds the circuit substrate 6 (7), and forms the heat conduction to the housing. The holding member 8 includes an elastically deformable spring part, and the spring part pressurizes itself against the housing thus pressurizes itself against the metal member 9, too.
