Zusammenfassung:A GIS-type zeolite containing carbon atoms in an amount of 4 mass% or less and having a silica-alumina ratio equal to or higher than 4.23, wherein at least one of conditions (i) and (ii) is satisfied in a spectrum obtained through X-ray diffraction. (i) 0.62≤A/B is satisfied, where A and B respectively represent the peak heights in the vicinities of 2θ=12.45 and 28.07°. (ii) 11.5≤B/C is satisfied, where B and C respectively represent the peak heights in the vicinities of 2θ=28.07 and 46.04°.
