Abstract: A honeycomb segment joined body includes a plurality of honeycomb segments; and joining layers for bonding side surfaces of the plurality of honeycomb segments. Each of the joining layers is a cured product of a pasty joining material, and has a standard deviation of joined widths of 0.30 or less. The honeycomb segment joined body is produced by applying pressurization with vibration when joining side surfaces of a plurality of honeycomb segments using a pasty joining material.

Abstract: A honeycomb filter including: a pillar-shaped honeycomb structure having an inflow end face and an outflow end face and including a porous partition wall disposed so as to surround a plurality of cells, the plurality of cells extending from the inflow end face to the outflow end face; inflow side plugging portions disposed at open ends of predetermined cells on the inflow end face side; and outflow side plugging portions disposed at open ends of residual cells on the outflow end face side, wherein the outflow side plugging portions comprise first outflow side plugging portions and second outflow side plugging portions, the plugging length L1 of the first outflow side plugging portions is 10 to 50% of the overall length L0 of the honeycomb structure, and the plugging length L2 of the second outflow side plugging portions is less than 10% of the overall length L0 of the honeycomb structure.
