1. A microwave induction heating device comprising:
a microwave input part configured to receive a microwave;
a microwave coupler connected to the microwave input part;
a dielectric resonator disposed to be spaced a predetermined distance apart from the microwave coupler and configured to operate based on a microwave received from the microwave coupler;
a metallic body disposed to surround the microwave input part, the microwave coupler, and the dielectric resonator to prevent leakage of the microwave to the outside; and
a microwave leakage prevention part coupled to the exterior of the metallic body and configured to block leakage of the microwave to the outside in an open space between the inside and outside of the metallic body,
wherein the microwave leakage prevention part comprises a form in which a plurality of rods for cavity resonance is erected in a direction parallel to the opening to be one-dimensionally or two-dimensionally arranged on a plate fixed along the exterior perimeter around the opening of the metallic body.
