Abstract

The present invention makes it possible to fix as much gas adsorbent or catalyst particles as possible to a gas adsorbing element or to a catalyst carrier having a honeycomb structure and also to improve the form-maintaining property of a honeycomb laminate after heat-treatment or during wet conditions so that operation becomes easy when impregnating the honeycomb laminate with a dispersion of gas adsorbent or catalyst particles. A honeycomb laminate is formed with paper including mostly ceramic fiber or glass fiber and mountain leather or with paper including mostly carbon fiber and mountain leather. The paper is then heat-treated, is impregnated with a dispersion of gas adsorbent or catalyst particles, is impregnated with a dispersion of inorganic binder such as silica sol or alumina sol, and is dried.
