PROBLEM TO BE SOLVED: To provide a surface light emitting laser element capable of high outputting.;SOLUTION: The surface light emitting element is provided with resonator spacer layers 103, 105 and an active layer 104. The active layer 104 contacting the resonator spacer layers 103, 105 between the resonator spacers 103, 105 is formed. The resonator spacer layer 103 consists of Ga_0.5In_0.5P that lattice matches. The active layer 104 consists of a quantum well structure where well layers 104B, 104D, 104F consisting of GaInPAs and barrier layers 104A, 104C, 104E, 104G consisting of Ga_0.5In_0.5P are alternately laminated. The resonator spacer layer 105 consists of (Al_0.7Ga_0.3)_0.5In_0.5P.;COPYRIGHT: (C)2007,JPO&INPIT
