Abstract
There is provided a honeycomb structurecomprising partition wallsseparating and forming a plurality of cellsfunctioning as fluid passages. The partition wallsare made of cordierite, and, when an average pore size of the partition wallsis x (μm) while a porosity of the partition wallsis y (%), a relation of x and y is y≦−8.33x+86.66 and satisfies 0.5≦x≦5 and 35≦y≦70. The honeycomb structurecan improve thermal shock resistance without sacrificing any of light-off performance, catalyst coatability, and strength.
