Beschreibung
Zusammenfassung:	An optical module, in which one or more grooves on which a plurality of optical fibers or optical parts are mounted, are formed to different depths and a stopper hole is manufactured so as to prevent a convex corner phenomenon so that an optical axis is precisely aligned, and a method of manufacturing the same are provided. The method of manufacturing an optical module includes the steps of first etching to form one or more grooves on a first surface of a wafer, and second etching to form one or more stopper holes so that a second surface of the wafer is etched to penetrate the wafer. The optical module having one or more grooves for mounting one or more optical parts on a substrate, includes stopper holes which are formed by penetrating the bottom surface of the substrate to center a region which corresponds to a predetermined region among the grooves.
