PROBLEM TO BE SOLVED: To provide a microwave heating device capable of measuring a temperature of the whole body to be heated, and then heating it even if the whole of the body to be heated cannot be seen from outside.;SOLUTION: A microwave heating device has: a housing part 10 in which a body 100 to be heated is installed; a coil 11 which is wound around a periphery of the housing part; an antenna 50 which irradiates the body to be heated with a microwave; a first oscillator 20 which generates an AC signal as a microwave to be radiated from the antenna; a second oscillator 30 which generates an AC signal to be input to the coil; and a control part 70 which calculates a temperature of the body to be heated based upon variation in inductance of the coil.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
