Abstract: A high-strength zeolite molding includes 10 parts by weight or more and 40 parts by weight or less of clay relative to 100 parts by weight of zeolite, and having a compressive strength of 20 N or more, in which the zeolite contains at least one zeolite that has Si/Al2 of 300 or more and 100000 or less and a water adsorption amount of 10 (g/100 g) or less under conditions of 25° C. and a relative pressure of 0.5, and the clay contains at least one clay that has a solid acidity of 0.15 mmol/g or less as determined by a NH3-TPD method. A method for producing includes kneading, molding, drying and disintegrating a product and then firing at 400° C. or higher and 700° C. or lower.
