PROBLEM TO BE SOLVED: To provide an organic electroluminescent element maintaining a high-efficiency luminous performance with an excellent visibility, an image forming device maintaining a luminous performance with high efficiency, a light-weighted mobile terminal for use of long period, and a manufacturing method of the organic electroluminescent element with high workability and productivity to be formed in a simple process. SOLUTION: The organic electroluminescent element, provided with at least a positive electrode 2 injecting holes, a luminous layer 4 having a luminous area, and a negative electrode 5 injecting electrons, on a substrate 1, is so structured that light irradiated from the luminous layer 4 is taken out from a light-taking-out face opposing the substrate 1 and a microlens group 6 consisting of almost hemispheric microlenses of at least two or more different sizes is formed on the light-taking-out face.
