A zeolite membrane composite for permeating and separating a highly permeable component from a gas mixture or liquid mixture comprising a plurality of components, the zeolite membrane comprising a CHA-type aluminosilicate zeolite, In the X-ray diffraction pattern obtained by irradiating with X-rays, the peak intensity around 2θ = 17.9 ° has a value less than 0.5 times the peak intensity around 2θ = 20.8 °, And the peak intensity around 2θ = 9.6 ° has a value of 2.0 times or more and less than 4.0 times the peak intensity around 2θ = 20.8 °, and is formed on the inorganic porous support. Being done. |
