Method capable of appropriately dividing ceramic molded body

The present invention provides a method capable of appropriately dividing a ceramic molded body. A method for dividing the ceramic molded body according to the present invention is a method for dividing a ceramic molded body in the thickness direction along a predetermined division position. The method includes a mounting step for horizontally mounting the ceramic molded body on an elastic body and a splitting step. In the splitting step, a split plate is abutted against a preset split position of the ceramic forming body loaded on the elastic body from the upper surface side. The split plateis press-fitted at a predetermined press-fitting amount of 1/3 or more and 9/10 or less of the thickness of the ceramic molded body; thus, a notch is formed in the ceramic molded body at the predetermined division position, and the ceramic molded body is divided at the predetermined division position by extending the crack from the lower end of the notch in the thickness direction of the ceramic molded body. 本发明提供一种能够适当地分
