Abstract
Provided is a laser module wherein any defective laser device can be isolated by performing burn-in on laser devices mounted on a mounting substrate. The laser module includes laser devices that emit laser light, a driver IC for driving the laser devices, a mounting substrate on which the laser devices and the driver IC are mounted, a common electrode terminal to which a common electrode of the laser devices is connected, individual electrode terminals to which individual electrodes of the laser devices are respectively connected, driver terminals to which the driver IC is connected, and test terminals which are respectively connected to the common electrode terminal and the individual electrode terminals, and to which an external power supply is to be connected when performing burn-in of the laser devices, wherein the number of the laser devices and the number of the test terminals are each larger than the number of the driver terminals.
