Abstract
To reduce bad connections of a BGA optical module as an optical fiber interface during mounting by reflowing. An optical module includes: a substrate to which an optical fiber is connected and fixed and on which an electronic circuit, an optical circuit or the like is formed; a ball grid array provided on one face of the substrate as an electrical interface used when the optical module is mounted on a mounting substrate; a lid having a thermal conductivity provided on another face of the substrate; and a fiber routing mechanism provided in contact with the lid, the fiber routing mechanism having a thermal conductivity and shaped to enable the optical fiber to be wound around the fiber routing mechanism.
