PROBLEM TO BE SOLVED: To efficiently utilize zeolite by preparing a zeolite molded product where zeolite has a ZSM5-type crystal structure and a metal component constituting the crystal skeleton is substantially silicon. SOLUTION: This binderless zeolite molded product where zeolite has a ZSM5-type crystal structure and a metal component constituting the crystal skeleton is substantially silicon alone or a combination of silicon and at least one metal element selected from the group consisting of iron, boron, chromium, cobalt, nickel, zinc and potassium and an atomic ratio of the metal element to silicon is 0.0001 to 0.5 is prepared. The molded product also has a specific surface area of 300-550 m2/g when measured by nitrogen absorption in the BET method, and a pore diameter of >=6 nm when measured by the method of mercury penetration, the pore surface area of 2-150 m2/g and the pore volume of 0.15-1.5 mL/g.
