Abstract
An object of an aspect of the present invention is to provide a new organic-inorganic hybrid membrane composite excellent in permeance and a relevant technique thereof. An organic-inorganic hybrid membrane composite in an aspect of the present invention includes a porous support layer and an organic-inorganic hybrid membrane formed on the porous support layer, an air permeation amount is 10000 L/(m2·h) or less, the organic-inorganic hybrid membrane contains a matrix polymer and a gas-selective inorganic filler, a contained amount of the gas-selective inorganic filler relative to the organic-inorganic hybrid membrane is 35% by mass or more, the gas-selective inorganic filler contains zeolite, a framework density in a case where all T elements of the zeolite are silicon is 16.0 T/1000 Å3 or less, and a membrane thickness of the organic-inorganic hybrid membrane is 0.05 μm or more and 50 μm or less.
