PROBLEM TO BE SOLVED: To provide a semiconductor substrate for a surface-emitting laser with improved high output and current supply, a surface-emitting laser, and a method for manufacturing the semiconductor substrate, at a low technical cost. SOLUTION: A semiconductor substrate (1), comprising an active layer (4) for causing emission light to emerge and a current supply layer (6) having a current block region (12) and a current pass region (13) and emitting emission light, having the vertical emission direction, is provided for a surface-emitting laser equipped equipped with an external resonator, and the external resonator has a predetermined resonator volume (14) that overlaps with the current passing region (13).
