Claim:
1. A vertical cavity surface emitting laser array comprising: a semiconductor substrate; a plurality of vertical cavity surface emitting laser element columns arranged in a row direction on a front-surface side of the semiconductor substrate; and parallel wiring lines that connect the plurality of vertical cavity surface emitting laser element columns in parallel with each other; wherein the plurality of vertical cavity surface emitting laser element columns each include a plurality of vertical cavity surface emitting laser elements arranged in a column direction, and a plurality of series wiring lines that serially connect every two of the vertical cavity surface emitting laser elements that are adjacent to each other in the column direction among the plurality of vertical cavity surface emitting laser elements in such an orientation that forward directions of the two vertical cavity surface emitting laser elements match, and a first insulating region that electrically insulates the plurality of vertical cavity surface emitting laser element columns from each other and a second insulating region that electrically insulates the plurality of vertical cavity surface emitting laser elements from each other are formed in the semiconductor substrate.
