Abstract

To provide a method for manufacturing a polyimide and/or a polyamide imide porous membrane with which it is possible to prepare a varnish in which microparticles are satisfactorily dispersed, even when minute microparticles are used, and to manufacture a porous membrane using the varnish. The method for manufacturing a polyimide and/or a polyamide imide porous membrane comprises a step for preparing a porous membrane manufacturing composition containing microparticles and at least one resin component selected from the group consisting of polyamic acids, polyimides, polyamide imide precursors, polyamide imides, and polyethersulfones, the preparation step including a dispersion step for causing a slurry containing the microparticles to disperse by shear and compression or shock.
