The invention discloses a microwave resonant cavity. The microwave resonant cavity comprises a cavity body and a film layer located on the surface of the inner wall of the cavity body. The film layer is made of a dielectric material capable of conducting heat. The internal film layer structure of the microwave resonant cavity has certain heat conductivity, heat generated at a hot spot of the conductive wall can be more effectively conducted to a low-temperature position far away from a heating spot, so that the maximum temperature rise at the hot spot is reduced, and the positive feedback effect caused by heat loss is further reduced; the internal film layer is a dielectric medium, is non-conductive, and almost does not interact with a microwave electromagnetic field, so that extra heat loss is not generated; the overall operation stability of the microwave resonant cavity is improved; the dielectric film with stable chemical property plated on the inner wall can also play a protection role, for example, magn
