PROBLEM TO BE SOLVED: To provide a method for producing a copper film having a predetermined pattern even without any etching step, and to provide a composition usable for the above method. SOLUTION: The composition comprises copper-based powder and water-glass. The method for producing the copper film comprises applying the above composition on a board by e.g. a printing technique such as screen printing technique or ink-jet technique, a spin-coating technique, a pattern-forming method using a dispenser, a spraying technique, and then baking the composition in a vacuum or inert gas at 300°C or higher.
