PPROBLEM TO BE SOLVED: To provide an organic field fluorescence element having a luminous layer containing a blue fluorescence compound capable of preparing a film in a wet film preparing process. PSOLUTION: The organic field fluorescence element having the luminous layer 5 containing the luminous compound between a pair of a positive electrode 2 and a negative electrode 9, wherein the luminous layer 5 is formed in the wet film preparing process, a luminous compound is a blue fluorescence compound with glass transition temperature of 80°C or higher and solubility of toluene of 0.2 wt.% or more, and has a molecular structure where at least a difference between a condensed ring (KK1) of 2 nuclei or 3 nuclei and a condensed ring (KK2) of 3 nuclei to 5 nuclei is 1 or more and 3 or less, and has an anthracene skeleton with preferably no substituent at the second place and a substituent containing 5 benzene rings or more at the sixth place.
