PROBLEM TO BE SOLVED: To provide a zeolite molded product enabling to form and maintain a zeolite film thereon without generating cracks and also satisfying both decrease in pressure loss and the maintenance and improvement of mechanical strength when used as a gas separation membrane such as a molecular sieve membrane, or an osmotic evaporating membrane, and also provided a zeolite laminated intermediate body which forms on the zeolite molded product a zeolite membrane containing a template, and further provide a zeolite laminated composite formed by calcining the zeolite laminated intermediate body, and still further provide a method for producing these efficiently. SOLUTION: This porous zeolite molded product has the difference of <=1.0 atm in pressure between the feeding and permeation sides in permeating amount of 10 ml/cm<2> per min when it has average particle diameter of 1.0μm or more, bending strength of 1.5 MPa or more and thickness of 1.8 mm.
