1. A three-dimensional electrical property measuring device comprising:
a well having a space for containing an electrolyte therein;
an insertion holder stacked on the well and having a through-hole at a center;
an ion-selective permeable membrane stacked on the insertion holder and having a porous structure; and
a non-uniform microchannel spaced apart from the ion-selective permeable membrane and inserted into the through-hole, and including a plurality of flow channels arranged in a three-dimensional lattice structure and through which a fluid passes,
wherein at least one of the plurality of flow channels has cross-sectional area that is different from cross-sectional areas of other remaining flow channels of the plurality of flow channels.
