Dielectric drying method and dielectric drying device for ceramic formed bodies, and method for producing ceramic structures

A dielectric drying device for ceramic formed bodies, the device comprising:

• an upper electrode;
• a lower electrode;
• and
• a conveying unit capable of conveying a plurality of ceramic formed bodies between electrodes of the upper electrode and the lower electrode, the ceramic formed bodies being placed side by side in an arrangement direction Y perpendicular to a conveying direction X on an upper surface of a drying table,
• wherein the upper electrode comprises:
• a central region;
• and two end regions between which the central region is located, in the arrangement direction Y;
• wherein the central region has a flat surface portion parallel to an upper end surface of the ceramic formed body,
• wherein each of the two end regions has an inclined portion inclined toward the lower electrode side;
• and
• wherein a ratio L2/L1 is from 0 to 1.70, in which L1 is a shortest distance between the central region and the ceramic formed body, and L2 is a shortest distance between each end of the two end regions and the ceramic formed body.
