Abstract:
1. An optical module holder comprising: an optical coupling section that optically couples an optical element and an end section of an optical transmission line; a cylindrical optical element attaching section for attaching the optical element at a position facing one optical function surface of the optical coupling section, said optical element attaching section being made of a UV transmitting material and having a thin-walled section; an optical transmission line attaching section for attaching the end section of the optical transmission line at a position facing another optical function surface of the optical coupling section; and an ultraviolet curable adhesive provided on said thin-walled section having a thickness less than or equal to 0.4 mm for bonding said optical element to said optical element attaching section; and wherein, when the optical element is adhered to the optical element attaching section by said ultraviolet curable adhesive through ultraviolet rays being irradiated onto the ultraviolet curable adhesive disposed on a predetermined disposal surface on an inner circumferential surface of the optical element attaching section so as to pass through the optical element attaching section from an outer side of the optical element attaching section, said thin-walled section maintains transmittance of the ultraviolet rays passing through the optical element attaching section at a predetermined value or higher to cure said adhesive.
