1. A gas separation membrane comprising:
a support;
a separation layer; and
a protective layer in this order,
wherein the separation layer contains inorganic particles,
the protective layer contains a resin and inorganic particles having an average particle diameter of 10 nm or greater which is less than 0.34 times the film thickness of the protective layer, and
the content of the inorganic particles contained in the protective layer is 40% by mass or less with respect to the content of the resin contained in the protective layer.
