A portion of the metallic foil (40) has a plurality of through holes (H). The honeycomb core (31, 31a, 31b, 31c, 31d) has a dense region (A) where the through holes (H) are densely formed, a zero region (B) where no through hole (H) is formed, and a boundary region (C) between the dense region (A) and the zero region (B) in an axial direction in which the exhaust gas (G) flows. The boundary region (C) is configured such that a total area of the through holes (H) in the boundary region (C) decreases gradually from near the dense region (A) toward the zero region (B)."
