ABSTRACT:
An object of the present invention is to provide a composite porous membrane, which has not only excellent filtration capacity, but also excellent adhesion between a porous membrane and a braid and mechanical properties, and a method for producing the composite porous membrane. The present invention relates to a composite porous membrane comprising a braid, and a membrane material; wherein the membrane material comprises a first porous layer comprising a dense layer which is arranged on the outer surface of the braid, and a second porous layer comprising a dense layer which is arranged on the first porous layer, and a method for producing the composite porous membrane.
