<p>An obj ect of the present invention is to provide a honeycomb structured body in which a crack in a cell wall that separates the cells of the honeycomb structured body hardly occurs when the honeycomb structured body is housed in the casing, and the honeycomb structured body of the present invention is a honeycomb structured body comprising one or a plurality of pillar-shaped honeycomb structural ceramic members, in each of which cells having a tetragonal shape or a shape similar to a tetragonal shape on a cross-section perpendicular to the longitudinal direction are placed in parallel with one another in the longitudinal direction with a cell wall therebetween, wherein a sealing material layer is formed on a peripheral portion of the honeycomb structured body, and on the cross-section perpendicular to the longitudinal direction in the honeycomb structural ceramic member, among cell walls, each of the cell walls that are continuously formed from the peripheral side of the honeycomb structured body toward the inside of the honeycomb structured body is allowed to form a straight line, where the straight line makes an angle from 55° to 90° relative to a tangent at an intersection with the peripheral edge of a honeycomb structural ceramic member which forms the peripheral portion of the honeycomb structured body.</p> |
