PROBLEM TO BE SOLVED: To provide an integrated semiconductor laser element which can improve a characteristic of a laser beam and reduce cost for optical axis adjustment and whose degree of freedom on an applying method of voltage is high. SOLUTION: The integrated semiconductor laser element is provided with a violet laser element 110 comprising a light emitting point 13 and having a projection 18 for positioning, and a red laser element 120 comprising a light emitting point 34 and having a recess 38 for positioning. The projection 18 for positioning the violet laser element 110 is engaged with the recess 38 for positioning the red laser element 120, in a state where an insulating film 12 and a solder layer 115a are installed between a p-side electrode 10 of the violet laser element 110 and a p-side electrode 31 of the red laser element 120.
