A dielectric drying method for ceramic formed bodies includes drying a plurality of ceramic formed bodies placed side by side in a direction perpendicular to a conveying direction on upper surfaces of drying tables by conveying the ceramic formed bodies between electrodes of an upper electrode and a lower electrode, and applying a high frequency between the electrodes. In the direction perpendicular to the conveying direction of the ceramic formed body, a distance between the electrodes in two end regions between which a central region is interposed is shorter than a distance between the electrodes in the central region.
