Spark discharge is generated between the two electrodes 1, 5, by applying a positive voltage and a negative voltage to the positive electrode 1 and the negative electrode 5 respectively from a direct current power source and also by applying a high-frequency voltage between the positive electrode 1 and the negative electrode 5. Owing to this spark discharge, plasma is generated between the positive electrode 1 and the negative electrode 5, and a plasma jet of high temperature and high speed bursts out of a plasma-jet nozzle 'b'.  After the plasma has become stable, spray powder is supplied from a spray-powder supply passage 8 to the plasma generating chamber. Because the powder is supplied in the same direction as the bursting direction of the plasma jet, heating and accelerating of particles are uniformized.
