A laminated structure having light-emitting units is formed on a single-crystal wafer. Electrode patterns are formed on the single-crystal wafer opposite the light-emitting units. Dummy patterns are formed on the single-crystal wafer at a location spaced apart from a location opposite the light-emitting units, and offset from a desired cleavage line intersecting the light-emitting units. A scratch is formed on the desired cleavage line. The wafer is cleaved, originating on the scratch, along the cleavage line orientation, in the direction from the dummy pattern, toward the light-emitting units.
