(57) [Summary] [Object] An object of the present invention is to provide a high-frequency heating device that has low noise and good cooling efficiency. [Structure] The blower 8 is configured to intake air from the bottom surface of the main body frame 10, and exhausts toward a cooling opening 7a of a high-frequency generator 7 and a cooled component 9b of a power supply device 9 provided at a position facing the blower. Thus, the power supply device 9, the high frequency generator 7 and the orifice 11 constitute an air passage. With this configuration, the noise leaked to the outside leaks only from between the bottom surface of the main body frame 10 and the product stand 12, so that the noise leaked to the outside is reduced. Further, since the air passage is formed, the object to be cooled can be cooled efficiently.
