Abstract

A semiconductor laser module is packaged on a mounting substrate through a thermal diffusion sheet member. The thermal diffusion sheet member is that having thermal conductivity where thermal conductivity in the surface direction is greater than that in the thickness direction. Specifically, the thermal diffusion sheet member is graphite, for example, and has a thermal conductivity of 300 W/m·K or greater in the surface direction.
