Abstract
A honeycomb structure body has an inner side base section and an outer side base section having a cylindrical shape. Inner side cells are formed in the inner side base section at a constant cell density. Outer side cells are formed in the outer side base section. A cell density of the outer side cells varies a radius direction. The outer side cells are formed on the basis of a relational equation of y=a(x−b)+c, where x is a distance on the outer side base section measured from a central point on a radial cross section, y indicates the number of the outer side cells per one cmat the distance x, a is a negative constant, b is a radius of the inner periphery of the outer side base section, c is the number of the inner side cells per one cm, and n is a degree.
