The present invention aims to provide a miniaturized optical laser module that eliminates shift in contacting surfaces when contacting and fixing with adhesive two element carriers respectively holding an optical element and obtains a smooth adhesion fixation. A semiconductor laser module that has a configuration in which the element carriers respectively arranged with optical elements for laser oscillation are contacted and securely attached to each other to optically connect the optical elements and form a semiconductor laser, and externally outputs a laser light to an optical fiber arranged in advance via an optical system; where collar parts for setting contacting areas to an enlarged state when contacting the element carriers and being removably configured are integrally arranged on each element carrier on both side end faces at a contacting surface of each element carrier.
