HONEYCOMB MOLDED BODY AND MANUFACTURING METHOD OF HONEYCOMB STRUCTURE
To provide a honeycomb molded body that can further suppress the occurrence of a crack during firing.SOLUTION: A honeycomb molded body containing a ceramic raw material comprising a columnar honeycomb structure having a plurality of rectangular cells defined by a partition wall and extending from a first bottom surface to a second bottom surface to form a flow path and an outer peripheral part having the outer peripheral part X in which the partition wall is covered with an outer peripheral wall and an outer peripheral part Y in which the partition wall is exposed, has a tapered part in which the outer peripheral part X gradually decreases in thickness as the outer peripheral part X approaches a boundary part with the outer peripheral part Y, and requires a length of one or more times the average cell pitch in an outer peripheral direction until the thickness of the outer peripheral wall is halved in the tapered part.SELECTED DRAWING: Figure 3-1
【課題】焼成時にクラックの発生を更に抑制可能なハニカム成形体を提供することを課題とする。【解決手段】隔壁によって区画形成され、第一底面から第二底面まで延びて流路を形成する複数の矩形セルを有する柱状ハニカム構造部と、前記隔壁が外周壁で被覆された外周部分Ｘ及び前記隔壁が露出した外周部分Ｙを有する外周部と、を備えたセラミックス原料を含有するハニカム成形体であって、外周部分Ｘは外周部分Ｙとの境界部分に近づくにつれて外周壁の厚みが漸減するテーパー部を有し、テーパー部においては、外周壁の厚みが半減するまでに外周方向に平均セルピッチの１倍以上の長さを要するハニカム成形体。【選択図】図３−１
