To provide a composition with which a metal film can be directly produced from a high-valent metal compound, a method for producing a metal film, and a method for producing a metal powder. n Using a composition for production of a metal film of copper, silver or indium, which comprises a high-valent compound of copper, silver or indium, a linear, branched or cyclic C 1-18 alcohol and a Group VIII metal catalyst, a coating film is formed, followed by reduction by heating to produce a metal film of copper, silver or indium. Further, using metal particles of silver, copper of indium having a surface layer comprising a high-valent compound of copper, silver or indium, instead of the high-valent compound of copper, silver or indium, a metal film of copper, silver or indium is produced in the same manner as above. |
