Claim:
1. A method of manufacturing a silicon carbide semiconductor device, said method comprising a metal film formation step of forming a metal film by: in a chamber suctioned by a vacuum pump, causing a high-frequency voltage to be applied between a pair of electrodes including an anode and a cathode that are arranged opposed to each other, to thereby cause a plasma of a sputtering gas to be generated between said pair of electrodes; sputtering a metal material placed on said cathode with an ion in said generated plasma; and causing said sputtered metal material to be deposited on a silicon carbide wafer that is placed on said anode so as to be opposed to said metal material, wherein, in said metal film formation step, said metal film is formed under a condition that an incident energy of incidence of said metal material and said sputtering gas on said silicon carbide wafer is lower than a binding energy of silicon carbide.
