Abstract
A method for manufacturing a zeolite membrane structure comprises an immersion step for immersing a porous substrate in a synthetic sol, and a synthesis step for hydrothermally synthesizing a zeolite membrane on a surface of the porous substrate that has been immersed in the synthesis so. When the foamability of the synthetic sol is measured by a Ross-Miles method under a condition of 25 degrees C., the foam height after elapse of 5 minutes from completion of down flow is less than or equal to 5 mm.
