A method for manufacturing an organic thin film element that includes an organic thin film between a pair of thin film electrodes and at least one electrode being a transparent electrode includes forming a transparent electrode by spraying a material liquid containing a transparent electrode formation material on a base material, and forming an organic thin film on the transparent electrode. This method allows for the manufacture of the organic thin film element by which an organic thin film element with high light-extraction efficiency is simply provided. A method for manufacturing an electro-optic device and a method for manufacturing electronic equipment that utilize the method for manufacturing an organic thin film element are described.
