A microwave oven includes openings and microwave dispersing apparatuses which are arranged to align with a magnetron in a row below a cooking cavity so as to reduce the overall size of a waveguide and uniformly reflect high-frequency electromagnetic waves to all regions of the cooking cavity. The center of a first opening is disposed at a downstream location away from the magnetron by a distance corresponding to one of odd numbers times a half-wavelength of a standing wave in the waveguide, while the center of a second opening is disposed at an upstream location which is offset from another distance away from the magnetron corresponding to another one of the odd numbers times the half-wavelength of the standing wave in the waveguide.
