An adapter 5 for an optical connector comprises a pair of wall portions 55a and 55b on a mounting surface 56a. The structure allows the adapter to accommodate an optical connector 4 inserted from a direction vertical to the mounting surface 56a, and allows the adapter to accommodate an optical connector 7 inserted along a predetermined axis 8. On this account, it is possible to insert the connector 7 along the predetermined axis 8 to the housed optical connector 4. Since the optical connector 4 is mated to and demated from the optical connector 7 in this sort of adapters, force applied to an optical module 2 is decreased in mating/demating the connector. An optical module product 9 includes the optical module 2, a coated optical fiber 3, the optical connector 4, and the optical connector's adapter 5. An optical module mounting substrate product 1 includes the optical module product 9 and a substrate 10 for mounting thereon the optical module 2 and the adapter 5 for optical connectors. IMAGE
