Abstract

A manufacturing method of a honeycomb structure includes a forming step of forming a quadrangular pillar-shaped honeycomb formed body, a firing step of firing the honeycomb formed body and forming a quadrangular pillar-shaped honeycomb fired body, a coating step of coating at least a part of side surfaces of the honeycomb fired body with a paste-like bonding material, a honeycomb block body preparing step of bonding the plurality of honeycomb fired bodies while performing pressurizing, to prepare a honeycomb block body, and a circumference grinding step of grinding a circumferential surface of the honeycomb block body and obtaining the honeycomb structure, and in the honeycomb block body preparing step, the bonding is performed without interposing any member other than the bonding material between the honeycomb fired bodies, and the bonding material has a shear thinning property.
