A plasma processing apparatus including a processing chamber for subjecting an object to plasma processing, a gas inlet, an evacuation device, a sample stage for the object, a power supply, and at least one induction coil. The at least one induction coil enables generation of the plasma in the processing chamber and is formed by connecting a plurality of identical coil elements in a parallel circuit-like arrangement so that current flows in each of the plurality of identical coil elements in a same direction when viewed from the sample stage.
