Beschreibung
Zusammenfassung:	One aspect of the present invention relates to a porous membrane having a porous structure, wherein when a fractal dimension is calculated under a plurality of conditions including at least two or more conditions, the fractal dimension being to be calculated from image data obtained by photographing a porous structure on a cut section formed by cutting the porous membrane on a discretionary section in which at least the porous structure is observed, at a discretionary photographing position and a discretionary photographing magnification at which at least the porous structure of the membrane section is observed, all of the fractal dimensions calculated under each of the plurality of conditions are 1.5 or more and 1.9 or less.
