In a microwave heating apparatus provided with a waveguide (32) for propagating a microwave from microwave generation means to a heating chamber, the waveguide having a square section orthogonal to a propagation route has a bent propagation route, and includes a pair of magnetic field surfaces facing each other, and a pair of electric field surfaces facing each other, and one of the magnetic field surfaces has a vertical surface (43), a horizontal surface (47), and a sloping surface (44) making predetermined angles with the horizontal surface and the vertical surface, the one of the magnetic field surfaces being provided with a mechanism (42) into which the microwave from the microwave generation means is introduced, and a mechanism (38) for radiating the microwave propagated through the waveguide to the heating chamber. |
