Abstract

The present invention provides a physical property evaluation device for a porous membrane capable of evaluating physical properties, a physical property evaluation method for a porous membrane, a porous membrane manufacturing device, and an air filter medium manufacturing method. This physical property evaluation device (50) for a porous membrane (31) comprises an evaluation unit (54e, 51) that obtains physical property evaluation data (54f) of at least one of the pressure loss and the membrane thickness of the porous membrane (31) on the basis of optical data (54a, 54b) of the porous membrane (31).
