PROBLEM TO BE SOLVED: To provide an electromagnetic wave heating device capable of maintaining a propagation mode of an electromagnetic wave in a specific mode to a change in physical property of a heated object by a simple configuration, and to provide an exhaust air cleaning device having the electromagnetic wave heating device.SOLUTION: An electromagnetic wave heating device 1 comprises: an electromagnetic wave generator 4 for oscillating at least a high-frequency electromagnetic wave; a cavity waveguide 2; an antenna 40 provided vertically to a longitudinal direction of the cavity waveguide 2; and electromagnetic wave reflection plates 5 and 6 provided at both ends of the cavity waveguide 2. In the electromagnetic wave heating device 1, a resonance cavity 20 is sectioned inside the cavity waveguide 2, and a dielectric heated object 3 housed inside the resonance cavity 20 is heated. In the reflection plate 5 that is an upstream side to the antenna 40 among the electromagnetic wave reflection plates 5 and 6, specific electric field shielding plates 7 protruding inward and shielding an electric field in a specific direction are provided. |
