Abstract
A light source-unit comprises a laser diode, a sub-mount which the laser diode is joined, and a heater which is joined on a joint surface of the sub-mount. The sub-mount comprises a pair of barrier-members. The barrier-members are formed with lower thermal conductivity material which thermal conductivity is lower than joining metal which is used for joining the laser diode and the sub-mount. The barrier-members are formed on the joint surface so as to sandwich the heater.
