<P>PROBLEM TO BE SOLVED: To provide a honeycomb substrate which contains zeolite in the surface without a binder and has excellent surface functions, including high-speed mass-transfer due to opening and a large surface area, and its manufacturing method. Ž<P>SOLUTION: The honeycomb substrate containing zeolite includes micro-pores of an opening area smaller than that of the honeycomb structure by at least 6 figures, in the surface of the honeycomb structure. The honeycomb substrate is preferably formed by depositing zeolite on the surface of the honeycomb structure. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
