ABSTRACT:
It is an object of the invention to effectively use semiconductor laser elements by suppressing difficulties caused by heat generated at the times of mounting and light emission in the semiconductor laser elements. A semiconductor laser module comprises a light source-mounting section, on which plural semiconductor laser elements are mounted and optical fiber-fixing section, which upports plural optical fibers at a predetermined lateral pitch. A pitch-converting section is provided between the light source-mounting section and the optical fiber-fixing section in order to respectively guide lights semitted from the semiconductor laser elements to the corresponding optical fibers. The light source-mounting section, the pitch-converting section and the optical fiber fixing section are formed on the same substrate.
