Abstract
A cell evaluation device includes: a porous membrane having a first main face and a second main face; a first passage having a first passage portion facing a first area on which cells are placed in the first main face of the porous membrane; a second passage having a second passage portion facing a second area in the second main face of the porous membrane, the second area being positioned backside of the first area; and a first electrode provided in the first passage portion and a second electrode provided in the second passage portion, the first electrode and the second electrode being positioned across the first area and the second area. In the cell evaluation device, tight junctions are formed among the cells by cell cultivation. With the cell evaluation device, any increase in the electric resistance occurring due to the formation of the tight junctions can be easily measured.
