A zeolite laminated composite of the present invention is characterized in that it has a separation membrane being constituted by a zeolite, and a porous substrate being constituted by a zeolite and having a catalyst function, and that the separation membrane is formed on the porous substrate. The composite shows a small pressure loss and hardly generates defects such as cracks in the separation membrane even under a high temperature condition.
