A microwave plasma processing apparatus includes a processing chamber; a microwave source that outputs a microwave; a dielectric plate that radiates the microwave output from the microwave source to the inside of the processing chamber; and a metal electrode provided on the side of a plasma-facing surface of the dielectric plate so as to be adjacent to the dielectric plate. Here, a part of the dielectric plate is exposed to the inside of the processing chamber at an outside of the metal electrode. Further, a cell area is defined as a virtual area that divides the ceiling surface of the processing chamber and is formed by two straight lines parallel to one diagonal line of the metal electrode and two straight lines parallel to the other diagonal line of the metal electrode and the cell area is a minimum rectangular area including the metal electrode and the dielectric plate.
