Abstract:
A method of producing a separator is provided. The method includes providing a particle membrane including inorganic particles on at least one principal surface of a porous body by a vapor-phase process such that the particle membrane has a porosity that is non-uniform in a thickness direction thereof. A method of producing a microporous membrane is also provided.
