摘要： Fine asperities are simply formed in the surface of a light emission surface to improve an luminous efficiency of a light emitting element. An LED element 10 is prepared as an example of a luminous body, and a thermally deformable heat mode recording material layer 12 is formed in the light emission surface 18 of the LED element 10. The recording material layer 12 is then illuminated with condensed light so that a plurality of recessed portions 15 are formed at a pitch of 0.01-100 times a center wavelength of the light emitted from the LED element 10.
