PROBLEM TO BE SOLVED: To provide a composite material for deposition in which an deposited film is obtained in a single deposition operation, having the initial composition of the deposition composed of aluminum in 100% and the post composition composed of metals A and B in total 100%. SOLUTION: A composite material for deposition has a composite structure provided with aluminum as outer layer and a metal A hard to deposite compared to aluminum as inner layer. A barrier layer composed of a metal B hard to depisite compared to the metal A is formed between the aluminum and metal A layers. The metal A is composed of at least one material selected from beryllium, tin, gold, chromium, iron, cobalt, nickel, silicon, titanium, vanadium, platinum, rhodium, ruthenium, molybdenum, carbon, niobium, osmium, tantalum and rhenium and the metal B is composed of at least one material selected from gold, chromium, iron, cobalt, nickel, silicon, titanium, vanadium, platinum, rhodium, ruthenium, molybdenum, carbon, niobium, osmium, tantalum, rhenium and tungsten.
