PROBLEM TO BE SOLVED: To provide a laser module capable of unifying a polarity of used LDs and solving the problems, such as a mistake in an LD mounting direction and time and labor required for component management, caused by the difference of polarities.SOLUTION: An electrode present at one end side of an LD unit 2 installed on one end side of a mount surface on an arbitrary stage of a heat sink 1 and an electrode present at the other end side of the LD unit 2 mounted on the other end side of the mount surface of a stage side lower than the arbitrary stage are electrically connected with a conductive member 7.SELECTED DRAWING: Figure 7 |
