Claim Text:
1. A semiconductor light emitting element comprising: a semiconductor laminate including a first semiconductor layer, an active layer and a second semiconductor layer which are laminated in descending order from an upper face to a lower face; a first electrode including a plurality of protrusions that penetrate the second semiconductor layer and the active layer, the first electrode being connected to the first semiconductor layer via the plurality of protrusions; a second electrode connected to the second semiconductor layer on an lower face of the second semiconductor layer; and an insulation film disposed between the plurality of protrusions and the semiconductor laminate, wherein the plurality of protrusions each include a protrusion body covered with the insulation film and a protrusion tip on the protrusion body, an upper face and a side face of the protrusion tip being exposed from the insulation film, the first semiconductor layer includes a plurality of recesses that are arranged on an upper face of the first semiconductor layer so as to sandwich first areas located above the respective plurality of protrusions, and a distance between the recesses sandwiching the first area is larger than a width of the protrusion tip, and wherein the protrusions are configured in an oval shape in a plan view.
