ABSTRACT:
There is disclosed a catalytic body with purifying efficiency and smaller pressure loss and its manufacturing method. Provided is a catalytic body wherein a porous honeycomb structure including partition walls defining a plurality of cells acting as fluid passages which extend through the honeycomb structure from one end surface to the other end surface thereof is formed of at least one type of (a) a catalytic substance and (b) a substance including an oxide and at least one type of noble metal carried on the oxide. The catalytic converter is characterized in that (c) 10% or more of a plurality of cells are plugged by plugging parts formed at one ends or in the middles of passages, that (d) the average pore diameter of the honeycomb structure is 10 μm or more, or that (e) the porosity is 40% or more.
