PROBLEM TO BE SOLVED: To provide a surface-emitting semiconductor laser that oscillates in a single horizontal mode, and can obtain a high-output laser beam, and its manufacturing method. SOLUTION: A surface-emitting semiconductor laser 100 includes a resonator 120. The resonator 120 is formed by laminating a lower mirror 102, an active layer 103, and an upper mirror 117. The upper mirror 117 includes first and second mirror parts 114 and 108. In a reflection factor adjustment layer 104, a part that is included in the first mirror 114 has film thickness for meeting Bragg reflection conditions, a part that is included in the second mirror 108 has film thickness for meeting anti-Bragg reflection conditions, and the reflection factor of the first mirror 114 is larger than that of the second mirror 108.
