HONEYCOMB STRUCTURE, HONEYCOMB CATALYST BODY USING THE SAME, AND MANUFACTURING METHOD OF HONEYCOMB STRUCTURE
[Problems] There is disclosed a technology which can load a large amount of catalyst, and enables the loaded catalyst to effectively exert a catalyst action. [Means for Solving the Problems] A honeycomb structure including porous partition walls 5 with which a plurality of cells 4 are formed, a porosity of the partition walls 5 is from 45 to 70%, and when pores 10 having the maximum width in excess of 10 µm in a cross section of each of the partition walls 5 which is parallel to a thickness direction Y of the partition wall are large pores 12 and the partition wall 5 is equally divided into three regions of a center region and surface layer regions present on both sides of the center region along the thickness direction Y, in the cross section of the partition wall 5 which is parallel to the thickness direction Y, a total area of cross sections of the large pores 12 which appear in the cross sections of the surface layer regions is from 60 to 100% of a total area of cross sections of all the pores 10 which appear in the cross sections of the surface layer regions, and a total area of cross sections of the large pores 12 which appear in the cross section of the center region is from 0 to 40% of the total area of cross sections of all the pores 10 which appear in the cross section of the center region.
