PROBLEM TO BE SOLVED: To provide a highly fine relief printing plate, with which a printed matter, the reproducibility of a printing area part of which is excellent even when an ink, which has a low viscosity and dissolves in an aromatic base solvent or halogen base solvent, such as for an organic EL element, is employed, by a method wherein the depth of a recess serving as the non-printing-area part is made more deeper than normal at the execution of highly fine printing by a relief printing method on a hard base material such as glass or the like and the manufacturing method of an electron device and an organic EL element. SOLUTION: The printing area part of the highly fine printed matter is lined up with a certain pitch width. Let the pitch width be a. A highly fine relief printing plate, the projected part serving as the printing area part of which has a pitch with the width of n×a (wherein n is an integer being at least 2) is produced so as to obtain the highly fine printed matter through the n-time transition of the highly fine relief printing plate.
