A method is provided for producing a DDR type zeolite membrane, including a membrane formation step of immersing a porous substrate having a DDR type zeolite seed crystal adhered thereon, in a raw material solution containing 1-adamantaneamine, silica (SiO2) and water, and conducting a hydrothermal synthesis of DDR type zeolite to form a 1-adamantaneamine-containing DDR type zeolite membrane on the porous substrate to produce a precursor of DDR type zeolite membrane-containing body, and a burning step of heating the precursor at 400° C. or above and at 550° C. or below to burn and remove the 1-adamantaneamine contained in the DDR type zeolite membrane.
