1. A microwave heating apparatus including:
a cavity resonator being a microwave irradiation space of a cylindrical type or a polygonal tube type where two parallel surfaces face each other with a tube central axis as the center, excluding a tube type whose cross-section in a direction perpendicular to the tube central axis is a rectangle; and
a transfer mechanism configured to supply an object to be heated of a magnetic substance, or a magnetic loss material or conductive material, or an object to be heated of a composite material including a magnetic substance, or a magnetic loss material or conductive material, into a space where energy distribution of a magnetic field in the cavity resonator is uniform in such a manner as to pass the object to be heated through a magnetic field region where magnetic field strength of the cavity resonator is maximum and uniform,
wherein the object to be heated supplied by the transfer mechanism is heated in the magnetic field region.
