A composite material with an electric contact layer includes a metal substrate, an adhesion layer formed-on a surface of the metal substrate, including an alloy including palladium (Pd) and a Y group metal as a main component selected from titanium (Ti), niobium (Nb), tantalum (Ta) and zirconium (Zr), and having an average thickness of not less than 5 nm and not more than 100 nm, and the electric contact layer formed on a surface of the adhesion layer, including a noble metal selected from gold (Au), platinum (Pt), rhodium (Rh), iridium (Ir) and silver (Ag), and having an average thickness of not less than 1 nm and not more than 20 nm.
