Abstract: PURPOSE: A substrate processing apparatus is provided to reduce a current flow which flows in a matcher or a current flow which flows from the matcher and to suppress heat generation, power loss, and the like. CONSTITUTION: A substrate processing apparatus(100) includes a high frequency power source(6), a plasma generation electrode(2), a single matcher(7), and an impedance control circuit(8). The high frequency power source generates high frequency power. The plasma generation electrode generates plasma by supplying the high frequency power from the high frequency power source. The single matcher is interposed between the high frequency power and the plasma generation electrode and matches an impedance of a load with an impedance of a transmission line. The impedance control circuit is interposed between the matcher and the plasma generation electrode and controls impedance between the matcher and the plasma generation electrode.
