Claim 0:
1. A honeycomb structure body, comprising a honeycomb body and a skin layer around the honeycomb body, the honeycomb body comprising axially-extending channels defined by a porous wall, wherein a radial path of a radial section of the honeycomb body from a central axis to the skin layer consists of a porous wall inner section and a porous wall outer section in sequence; an average wall thickness of inner porous walls provided in the porous wall inner section is smaller than an average wall thickness of outer porous walls provided in the porous wall outer section, and a length of the porous wall inner section in the radial path accounts for 80%-95%;
a pore density of the inner porous walls is approximately the same as that of the outer porous walls;
the inner porous walls have a wall thickness of 0.15 mm-0.40 mm; a maximum thickness of the inner porous walls is not greater than a minimum thickness of the outer porous walls;
a ratio of the average wall thickness of the inner porous walls to the average wall thickness of the outer porous walls is 1:1.1-1.8;
the skin layer has a thickness of 0.5 mm-1.1 mm.
