摘要： A waveguide filter for use in a microwave oven having a plurality of metallic plates disposed in a waveguide in substantially parallel to side walls of the waveguide. The metallic plates are provided in the upper and lower edges thereof with a series of openings at a constant interval so as to provide a corrugated configuration. First members are disposed for providing a certain spacing between adjacent ones of the metallic plates and holding the metallic plates substantially in parallel to one another; and second members including metal members are disposed between the side walls of said waveguide and the ones of the metallic plates adjacent the waveguide side walls for creating a substantially uniform clearance between the upper and lower edges of the metallic plates and the upper and lower walls of the waveguide and for holding the metallic plates substantially in parallel to the waveguide side walls.
