PROBLEM TO BE SOLVED: To provide a fine light-emitting element that is capable of irradiating light with strong intensity in the region of a shorter width than the wavelength of the light source. SOLUTION: The fine light-emitting element comprises a pair of planar electrodes that are formed on an insulating substrate and a luminous part that emits light by being impressed with a voltage by the above-mentioned planar electrodes. The shortest distance between the planar electrodes is made shorter than the wavelength of the light emitted by the above luminous part. When, for example, Alq3 , is used as an organic EL membrane for the luminous part, the wavelength of the emitting light is approximately 515 nm and at least one of the shortest distance between the electrodes or the width of the electrodes is made shorter than this length.
