Abstract
In a green honeycomb molded body including a columnar body of the green honeycomb molded body in which a plurality of hexagonal cells mutually partitioned by partition walls are open at an end surface of the columnar body, a center closing jig is inserted into a part of a plurality of cells at the center of the end surface to join partition walls to each other using the center closing jig, thereby closing the cells at the center of the end surface and the outer periphery of the end surface including the plurality of cells is pressed by a cylindrical outer periphery closing jig having an inner peripheral surface with the inner diameter being continuously reduced from one end to the other end, thereby collapsing the cells at the outer periphery of the end surface to close the cells at the outer periphery of the end surface.
