    Abstract: A microwave plasma processing device (100) of the slot antenna type includes a planar antenna plate (31) constituting a flat waveguide and a cover (34) formed by a conductive member. The cover (34) has a stub (43) as a second waveguide for adjusting field distribution in the flat waveguide. The stub (43) is arranged at a position superposed by slots (32) constituting a slot pair arranged at the outermost circumference of the planar antenna plate (31) when viewed from above. By appropriately arranging the stubs (43), it is possible to control the field distribution in the flat waveguide and generate a uniform plasma.
