Abstract
A honeycomb filter includes a pillar-shaped honeycomb structure integrally formed, first and second lamination members, a metal casing containing the honeycomb structure and the lamination member, and first and second end members connected to first and second end portions of the casing, respectively to secure the honeycomb structure and the lamination member. The honeycomb structure includes a wall portion defining through holes which extend substantially along a longitudinal direction of the honeycomb structure, each of the through holes being sealed at either one end portion. Each of the lamination members has aligned through holes extending substantially along the longitudinal direction. The honeycomb structure and lamination members include inorganic fibers oriented substantially perpendicular to the longitudinal direction. The lamination members are provided at first and second end faces of the honeycomb structure, respectively to align the aligned through holes with the through holes of the honeycomb structure.
