A semiconductor light emitting element includes a first conductive layer, a second conductive layer, and an active layer provided between the first conductive layer and the second conductive layer. The first conductive layer has a current constriction structure, a current injection region being constricted in the current constriction structure. The active layer includes a plurality of quantum well layers, a first light emission wavelength being in a wavelength range of an intensity peak of an entire light emission spectrum, the first light emission wavelength corresponding to a light emission recombination level energy gap of a first quantum well layer of the plurality of quantum well layers, the first quantum well layer being provided at a position closest to the current constriction structure.
