Abstract: In a honeycomb structure used as an exhaust gas purification filter for a diesel vehicle, it is necessary to conduct a regeneration treatment for burning off remaining carbon microparticles. During this treatment, a local temperature rise cannot be avoided, and hence there is present the problem that a high thermal stress and cracking are easily generated. A bonding layer 12 is provided with a low porosity portion and a high porosity portion, and the positions thereof are controlled, whereby when a bonding portion is broken, the progressing site of a crack is guided to the high porosity portion and the crack is inflected in the high porosity portion, with the result that the breakage of the bonding layer 12 scarcely occurs and progress of the crack can be controlled. Thus, a joined body having the above constitution and a manufacturing method thereof have been found.
