能な遮光ケースと、該ケースに収納可能な光素子から構
成されていた。Conventionally, an optical transmission/reception module for an optical data link used for optical transmission has been composed of a light-shielding case that can be coupled to an optical connector having an optical fiber, and an optical element that can be housed in the case.

、光結合損失を生じるという欠点もある。The conventional optical transmitter/receiver module for optical data links described above has a light shielding case that can be connected to an optical connector and an optical element that can be stored in the case, so there is a limit to how small and thin they can be when combined. . Another disadvantage is that the optical element and the light-shielding case may be misaligned due to impact or the like during use, resulting in optical axis misalignment and optical coupling loss.

樹脂のズレによる光結合損失がないという効果もある。As explained above, the present invention has a double-molded structure in which the optical element is first molded with a transparent resin and then the outside is secondarily molded with a light-shielding resin, so the conventional optical element is inserted into a light-shielding case. It is possible to make the device smaller and thinner than the other methods. In addition, in the conventional method, there is a misalignment between the optical element and the light-shielding case during use, resulting in optical coupling loss, but in the present invention, the transparent resin containing the optical element and the light-shielding resin are completely in contact with each other. Therefore, there is also the effect that there is no optical coupling loss due to misalignment between the transparent resin containing the optical element and the light-shielding resin.
