A spray coating apparatus includes a cathode and an anode nozzle to form a pair. A front end of the anode nozzle is provided with three or more plasma jet jetting holes, and a spray material jetting hole is disposed at the center of an area surrounded by the plasma jet jetting holes. The spray material jetted through the jetting hole is fed into the center axis of a complex plasma arc or a complex plasma jet. The spray material jetted through the spray material jetting hole is melted at high thermal efficiency, to thereby enhance yield of coating film. Reflection of the spray material by the outer periphery of plasma flame, penetration of the spray material through plasma flame, and scattering of the spray material caused by reflection or penetration, due to the differences in particle diameter, mass, etc. of the spray material is prevented.
