PROBLEM TO BE SOLVED: To stably keep tile body in a self-supporting state and to prevent the fall of the tile body in firing by flat grinding the contact part of the tile body prior to firing even if the tile body is distorted by shrinkage due to drying in the production of a clay tile. SOLUTION: When molded tile body 10 is dried and fired in a self-supporting state to produce a clay tile, the contact part 22 of the dried clay body 10 on the bottom 14 side is flat ground so that the clay body 10 can self-support and the clay body 10 is allowed to self-support through the ground contact part 22 and fired in the self-supporting state.
