摘要

PROBLEM TO BE SOLVED: To provide a method for forming a functional membrane pattern by which a fine membrane pattern can be formed and whose process is simplified, and to provide a method for forming the functional membrane pattern by which such defects as disconnection and short-circuit are hardly generated and a pattern with a thick thickness and being advantageous for exhibiting such a function as electric conductivity can be formed. SOLUTION: A method for forming the functional membrane pattern by discharging a liquid containing a functional ingredient such as an electrically conductive fine particle on a base sheet 101 by means of ink-jet is provided with a process (S2) in which the liquid is applied by the ink-jet on the base sheet with a functional membrane forming face with a contact angle to the liquid of 30-60 degrees, and a process (S3) for converting the applied liquid to a functional membrane by heat treatment. In the discharging process by the ink-jet, it is preferable that overlapping of 1-10% of the diameter of the liquid when the liquid is applied on the base sheet is generated.
