Abstract
An optical transmission module includes a substrate having an opening portion; an optical element closing an opening on the lower surface side of the substrate and converting an electric signal into an optical signal or the optical signal into the electric signal; an optical fiber transmitting the optical signal; a ferrule closing an opening on the upper surface side of the substrate and having an optical fiber insertion hole; and a resin filled into a space surrounded at least by the substrate, the optical element, the ferrule, and a distal end of the optical fiber, wherein the ferrule has a resin filling hole spaced apart from the optical fiber insertion hole to fill the space with the resin, and an angle formed by an axis of the optical fiber insertion hole and an axis of the resin filling hole is equal to or more than 0° and less than 90°.
