Abstract:
1. A manufacturing method of a honeycomb structure, comprising: subjecting a raw material to extrusion forming to obtain a honeycomb formed body having a partition wall that partitions a plurality of cells that serve as flow paths for a fluid and are extended from one end surface to an other end surface; forming a plurality of notches extended in a direction along which the cells are extended in the honeycomb formed body to form a partial segment aggregate in such a manner that a plurality of partial segments are partitioned; and forming a buffer portion between respective partial segments adjacent to each other in the partial segment aggregate to fill an entire space between the respective partial segments adjacent to each other, thereby obtaining a honeycomb structure; wherein a plurality of notches are formed in a central portion, located between two opposing end portions of the honeycomb formed body, in a central axis direction of the honeycomb formed body to form a partial segment aggregate while leaving both of the end portions uncut.
