Abstract: An optical module includes a base portion having a top-surface metal layer on a top surface of a base, a semiconductor element on the top-surface metal layer and an optical element optically-coupled to the semiconductor element and bonded to the base with adhesive at a first side surface of the base at a side of the optical element being optically-coupled. A pull-back area is formed on the top surface by disposing a second side surface at the side, of the top-surface metal layer at a retracted position to the first side surface at the side. Between an adhesion area where the base and the optical element are bonded and a mounting portion below an optical-power-outputting surface of the semiconductor element, the top-surface metal layer has an adhesive flow stopping portion formed, by patterning, so as to prevent the adhesive from flowing through the pull-back area to the mounting portion's side.
