In a laser chip 1 using a nitride semiconductor having a hexagonal crystal structure, the −c plane is used as a first resonator facet A, which is the side of the laser chip 1 through which light is emitted. On the first resonator facet A, that is, on the −c plane, a facet protection film 14 is formed. This ensures firm joint between the first resonator facet A and the facet protection film 14 and alleviates deterioration of the first resonator facet A.
