PROBLEM TO BE SOLVED: To provide a laser element that has an extremely small amount of unevenness and comprises a nitride semiconductor having a resonance surface being close to a mirror, and to provide a manufacturing method of the resonance surface of the laser element. SOLUTION: The cleavage surface of one kind of orientation out of face 1 (1/100), face 2 (10/10), face 3 (01/10), face 4 (/1100), face 5 (/1010), and face 6 (0/100) of a nitride semiconductor is set to be at least one resonance surface, thus providing the resonance surface close to a mirror.
