ABSTRACT:
A honeycomb structure body has a plurality of hexagonal cells of a hexagonal shape formed in a lattice arrangement. Each hexagonal cell is surrounded by its hexagonal cell wall composed of six sides. On a cross-sectional surface along the axis direction of the ceramic honeycomb structure body, each side in the six sides forming the hexagonal cell wall surrounding the corresponding hexagonal cell is a concave shape toward either the inside of or the outside of the hexagonal cell. In particular, it is preferred that continuous three sides in each hexagonal cell wall has a concave shape that is concave toward either the inside or the outside of the hexagonal cell, and the remaining continuous three sides in the cell wall has a concave shape that is concave toward the opposite direction to the direction of the concave shape formed by the above continuous three sides.
