Abstract
A method for manufacturing a laser diode element includes preparing a stacked body including a nitride semiconductor substrate, a first conductivity type semiconductor layer, an active layer, and a second conductivity type semiconductor layer. Element regions are defined by planned cleavage lines and planned division lines. The stacked body defines protrusions each including first and second side surfaces, and a ridge. Lower ends of the first and second side surfaces are located below a lower surface of the active layer. A first distance from the first side surface to the ridge is different from a second distance from the second side surface to the ridge. The first distance is the same for all of the protrusions in the at least one of the element regions. The stack body is cleaved from the first side surface to the second side surface.
