Abstract
A semiconductor laser module having a package containing a semiconductor laser device and lead pins provided on both the side surfaces of the package . Since a base end portion of the lead pin is fixed to the side surface at a position higher than the bottom surface of the package , the lead pin can be laterally bent at a position higher than the bottom surface. Therefore, the semiconductor laser module can be mounted on the surface of the wiring board while the bottom surface of the package is in close contact with the wiring board . Thus, since a heat radiation path from the bottom surface of the package to the wiring board is secured, it is possible to reduce the instability in the operating characteristic of the semiconductor laser device due to the thermal effect.
