Abstract
Provided are a ceramic separation membrane structure improved in separation performance with no reduction in permeability, and a method for producing the structure. The ceramic separation membrane structure includes a ceramic porous body, a zeolite separation membrane disposed on the ceramic porous body, and a repair portion made of a repairing material of organic-inorganic hybrid silica. The organic-inorganic hybrid silica is a combination of an organic component and a silicon-containing inorganic component.
