Abstract
An optical module comprises an optical connector, to one end of which one end of an optical fiber is connected; an optically operating element secured to the optical connector, the optically operating element being optically coupled to the optical fiber; electronic circuit elements forming an electronic circuit connected to the optically operating element; a substrate bearing the electronic circuit elements;
lead pins consisting of inner and outer leads, the inner leads being connected to the electronic circuit; and a molded resin member holding as one unit the optical connector, the optically operating element, the electronic circuit elements, the substrate and the lead pins except the one end of the optical connector and the outer leads of the lead pins. The optical module is manufactured using a lead fram comprising a plurality of lead parts which are formed into the lead pins later; a frame part for supporting the lead parts; a substrate forming part supported by a few of the lead parts;
and a holding member for holding the optical connector.
