摘要：
A laser light source device includes: a laser light source module; a pipe through which a cooling refrigerant flows; a heat block which thermally joins the laser light source module and the pipe to each other; and a vessel which is arranged below the heat block and receives dew condensation water which is generated on a surface of the heat block by condensation and drops. The vessel has an opening portion which opens upward, and a plan view profile of the opening portion is larger than a plan view profile of the heat block.
