Abstract
There are disclosed a honeycomb structure capable of providing a honeycomb catalytic body which is excellent in purification efficiency with a small pressure loss and which can be mounted even in a limited space, a honeycomb catalytic body which is excellent in purification efficiency with a small pressure loss and which can be mounted even in a limited space, and a manufacturing method of the same. A honeycomb catalytic body 50 of the present invention is a honeycomb catalytic body of a flow-through type through which cells as through channels extend from an inlet to an outlet, both the surfaces of partition walls 4 of a honeycomb structure 1 and the inner surfaces of pores 25 carry a catalyst to form catalyst layers 5, and the catalyst carrying partition walls have a permeability of 1×10−12 [m2] or more, preferably 1×10−9 [m2] or less.
