PROBLEM TO BE SOLVED: To provide a manufacturing method of a semiconductor laser of which a semiconductor laser that degrades due to energization of element current is decreased to decrease a manufacturing cost. SOLUTION: The manufacturing method of a semiconductor laser which is formed from a compound semiconductor layer in which a ridge contains Ga, includes a process (step 12) wherein the semiconductor laser is energized with element current until the characteristics of the semiconductor laser is restored after it is degraded by energization of the element current.
