Patent ID: 7171066

Claim:
An optical module comprising: a base portion; a surface type optical element receiving or emitting light; an optical waveguide being mounted on the base portion, the optical waveguide having on a first end portion of the optical waveguide light input/output end face that transmits light therebetween; a holding member being mounted on the base portion, the holding member positioning and holding the surface type optical element and the first end portion of the optical waveguide; a cap being mounted on the base portion, the cap having a light transmitting window provided in a position opposing to a second end portion of the optical waveguide, the cap at least partially covering the optical element and the optical waveguide; and a fixing member that fixes the second end portion of the optical waveguide to the light transmitting window of the cap wherein the fixing member has a first through-hole for positioning the surface type optical element by inserting the surface type optical element into the first through-hole and a second through-hole for positioning the optical waveguide by inserting the optical waveguide into the second through-hole.
