Patent ID: 8040675

Claim:
An optical module comprising: a case; an optical transceiver to perform one or both of transmission and reception of an optical signal, the optical transceiver being arranged in the case and having a cylindrical member thereon; a radiator to radiate heat of the optical transceiver to outside of the optical module, the radiator being arranged on the case; a thermal conductive sheet having a property of transferring heat to a surface direction and in the horizontal direction, and the thermal conductive sheet being elastic and having a first end and a second end; a first fixer to fix the first end of the thermal conductive sheet to the optical transceiver, the first fixer having a hole; and a second fixer to fix the second end of the thermal conductive sheet to a radiating point, wherein the cylindrical member of the optical transceiver is fitted into the hole of the first fixer so that the thermal conductive sheet is folded onto the optical transceiver.
