PROBLEM TO BE SOLVED: To solve the problem that a vertical resonator-type semiconductor light emitting element has high thermal resistance because the semiconductor light emitting element is small in size, and a DBR mirror forming a reflecting mirror is low in thermal conductivity, therefore an active layer rises in temperature by heat released when a current is applied, and it is difficult for the semiconductor light emitting element to output high power. SOLUTION: A groove is cut in around a light emitting part as deep as a current constriction part, and an electrode is formed direct on the groove. By this setup, a distance from a heat releasing part to the electrode is shortened, and heat is easily conducted in a lateral direction.
