Claim 0:
1. A method for producing a catalyst structure comprising:
baking a precursor material (B) including a precursor material (A) which is for obtaining a carrier of a porous structure composed of a zeolite compound and is impregnated with a solution containing a metal;
hydrothermally treating a precursor material (C) obtained by baking the precursor material (B); and
subjecting the hydrothermally treated precursor material (C) to reduction treatment to produce the catalyst structure that includes
the carrier having the porous structure comprising the zeolite compound having a framework, and
at least one catalytic material comprising a fine particle of the metal and existing in the carrier,

wherein the carrier has a plurality of channels communicating with each other, the channels include at least one of a one-dimensional pore, a two-dimensional pore and a three-dimensional pore defined by the framework of the zeolite compound, and a plurality of enlarged diameter portions which are different from the one-dimensional pore, the two-dimensional pore and the three-dimensional pore and are not defined by the framework of the zeolite compound, and
the catalytic materials are included in the enlarged diameter portions such that one of the enlarged diameter portions encloses one of the catalytic materials and separates the one of the catalytic materials from another of the catalytic materials.
