Patent ID: 8241555

Claim:
A method for manufacturing a honeycomb structure, comprising the steps of: subjecting a forming raw material to extrusion forming to obtain a segment-joined type honeycomb formed article provided with a plurality of honeycomb segments extending from one end face to another end face and an outer peripheral portion surrounding a whole outermost periphery of the plurality of honeycomb segments; forming a slit-shaped gap extending from one end face to the other end face between adjacent segments, adjacent honeycomb segments are joined by a belt-like joining rib extending from one end face to the other end face and having a thickness of 0.1 to 1.5 mm, and the honeycomb segments have partition walls separating and forming a plurality of cells extending from one end face to the other end face and functioning as fluid passages, wherein the joining rib is obliquely joined or folded; firing the honeycomb formed article to form a honeycomb fired article; destroying the joining rib in the honeycomb fired article; and forming a buffer portion by filling a bonding material in the gap.
