Claim:
1. A vertical cavity surface emitting laser comprising: a substrate; a laminated body which is provided over the substrate; and a resin layer which is provided on at least an entire outer wall of the laminated body and a portion of the top of the laminated body; and an electrode provided over a portion of the top of the resin layer and over a portion of the top of the laminated body, wherein the laminated body at least includes a first mirror layer provided over the substrate, an active layer provided over the first mirror layer, and a second mirror layer provided over the active layer, in a plan view, a first maximum length of the laminated body in a first direction is greater than a second maximum length of the laminated body in a second direction orthogonal to the first direction, in the plan view, a first maximum length of the resin layer in the first direction is greater than a second maximum length of the resin layer in the second direction, in the plan view, the laminated body includes a first portion, a second portion, and a third portion provided between the first portion and the second portion, the first portion and the second portion face each other in the first direction, in the plan view, a length of the third portion in the second direction is greater than a length of the first portion in the second direction or a length of the second portion in the second direction, in the plan view, an outer rim of the resin layer includes a first straight edge, a second straight edge facing the first straight edge, a first curved edge which connects the first straight edge and the second straight edge to each other, and a second curved edge which faces the first curved edge and connects the first straight edge and the second straight edge to each other, in the plan view, the first portion and the first curved edge are positioned on the same side of the third portion, and in the plan view, when an end of the first straight edge coming in contact with the first curved edge is set as a first end, an end of the second straight edge coming in contact with the first curved edge is set as a second end, and a first virtual straight line passing through the first end and the second end is drawn, an end portion of the first portion is positioned on the third portion side of the first virtual straight line.
