Abstract
The object is to provide a technique that allows a semiconductor laser to be efficiently cooled. A semiconductor laser light source device includes: a semiconductor laser; a cooler that cools the semiconductor laser; and a driving substrate that drives the semiconductor laser. The cooler is placed in contact with a surface of the semiconductor laser that is opposite to a light emitting surface of the semiconductor laser. Furthermore, the driving substrate is placed in contact with a surface of the cooler that is opposite to a surface of the cooler on which the semiconductor laser is placed.
