Abstract:
Disclosed is a honeycomb structural body capable of suppressing the occurrence of defects. The disclosed honeycomb structural body (200) is provided with a honeycomb-shape columnar body (170) having multiple roughly parallel through-holes (70a) and separating walls (170c) separating said through-holes (70a), and sealing sections (170b) which seal one end of the through-holes (70a). Some of the through-holes (70a) are sealed by the sealing sections (170b) at a first end of the columnar body (170), said first end being roughly perpendicular to the through-holes (70a), and open at a second end; the other through-holes (70a) are sealed by the sealing sections (170b) at the second end and open at the first end. The columnar body (170) and the sealing sections (170b) contain a ceramic which is aluminum titanate-based and/or cordierite-based, and the separating walls (170c) and the sealing sections (170b) form a single body.
