Abstract
A bonded honeycomb segment assembly has plurality of honeycomb segments each including cell structure having plurality of cells as fluid passages partitioned by porous partition walls and provided in parallel with one another, and outer wall provided in the outer periphery of the cell structure. The outer wall of each of the plurality of honeycomb segments is bonded to one another via bonding layers. Relation of M<Mis satisfied in which Mis compressive Young's modulus in thickness direction of the bonding layers positioned in the vicinity of gravity point in cross section of the bonded honeycomb segment assembly perpendicular to the fluid passage direction of the cells, and Mis compressive Young's modulus in the thickness direction of the bonding layers bonding the outer wall of each of the plurality of honeycomb segments positioned in the outermost periphery of the bonded honeycomb segment assembly.
