Abstract
The present invention provides a method for manufacturing a honeycomb structure, the method including steps of: forming, by extrusion, a formed bodyhaving an outer wall, partition walls provided inside the outer wall, and cells each surrounded by the partition walls as well as extending to an axial direction of the body; and drying the formed body. The method for manufacturing the honeycomb structure is characterized in that the forming step includes receiving the formed body on a cradlewhich receives the formed body so that an angle of a faceof the outer wall on the cradlerelative to the horizontal plane is 15 to 35 degrees, a cradle which has a V-shaped cross section with a cut at an apex of the V shape and which receives the formed body so that the angle relative to the horizontal plane is 15 to 45 degrees, or a cradle which receives one face of the formed body and characterized in that the drying step includes drying the formed bodyin a state of being received on the cradlehaving the predetermined angle. The method for manufacturing the honeycomb structure reduces distortion and deformation of the honeycomb structure.
