Abstract: PURPOSE: To heat a sheet-like material web uniformly so as to removed surface volatile solvent by passing a web whose thickness is smaller than the wavelength of a microwave standing wave through a microwave standing wave area in which the wavelengths are shifted by 1/4 wavelength as causing carrier gas to flow. CONSTITUTION: Microwave standing waves 3, 4 of predetermined frequencies which are shifted by 1/4 wavelength along the moving direction 19 of a web 1 are supplied to two respective conduction rods in a processing step 2. By an electric field based on the same the web 1 having a smaller thickness than the wavelength of the microwave frequency is heated in the step. By standing waves 3, 4 shifted by 1/4 wavelength the standing waves 3, 4 are not coupled with each other so that the web is uniformly heated and volatile solvent on the surface of the web is excellently removed by carrier gas.
