PROBLEM TO BE SOLVED: To enable properly adjusting front luminance of colored light each emitted from each luminescent layer provided in a surface luminescent element, in a surface emitter equipped with a surface luminescent element in which the light emitting surface of a translucent substrate to emit light is provided and luminescent layers to emit light having a plurality of different wavelengths are provided on the opposite side surface. SOLUTION: In this surface emitter equipped with the surface luminescent element 10 in which the light emitting surface 11a of the translucent substrate 11 to emit light is provided, and the luminescent layers 14a, 14b, 14c to emit light having a plurality of different wavelengths are provided on the opposite side surface, luminance characteristics of light distribution from the luminescent layers in the surface luminescent element are differentiated from others in accordance with the wavelength of emitted light, and a translucent condensing plate 21 having recessed and projecting parts 21a on its surface is provided on the light emitting surface of the translucent substrate.
