PROBLEM TO BE SOLVED: To have a problem that the wiring resistance of a transparent or semi-transparent electrode in an organic semiconductor element such as an organic photoelectric conversion element or an organic EL is large, and electrical noise or uneven brightness is generated to impair the quality. The present invention is an organic patterning layer arranged outside a transparent electrode in an organic semiconductor element, and the organic patterning layer is characterized in that an organic compound constituting the organic patterning layer has the following characteristics. The present invention relates to a metal patterning method, which comprises arranging the organic patterning layer on the outside of a transparent electrode in an organic semiconductor element and selectively forming a metal film in a wiring area of a non-transmissive portion. a. The static contact angle (temperature / humidity: 23 ° C., 50%) with respect to 1 μL of pure water when the film was formed was 85 ° or more, and b. The glass transition temperature (Tg) is 100 ° C. or lower, and c. It is a small molecule with a molecular weight of 1000 or less. [Selection diagram] Fig. 1 |
