An extracellular potential measurement device includes multiple insulating films each of which is made from an electric insulating material, the insulating films being stacked and bonded to each other; and multiple electrode wires each of which is made from an electroconductive material, the electrode wires being arranged in multiple heights. Each of the electrode wires is interposed between an upper insulating film and a lower insulating film. Each of the insulating films, except for a lowermost insulating film, has an opening penetrating the insulating film. The opening in a lower insulating film has a size that is less than that of the opening in an upper insulating film, the openings in the insulating films being overlapped to form a recess having a size reducing downward, the recess being adapted to store a collection of cells. Each of the electrode wires has an end that is located near an opening in an insulating film that is immediately below the electrode wire, the ends being exposed in the recess.

A cell capture apparatus includes a cell separation unit having a flat plate shape and a cell capture unit having a flat plate shape located therebelow. A liquid sample and a carrier liquid flow in a cell-separation flow passage of the cell separation unit. The liquid sample contains multiple large cells, multiple small cells, and a sample liquid component. The cell-separation flow passage separates a set of large cells and the carrier liquid from a set of small cells and the sample liquid component. The cell capture unit includes a large-cell flow passage in which the set of large cells and the carrier liquid flows, and multiple electrode wires for attracting the large cells by means of dielectrophoresis. Multiple cell capturing wells are formed in the large-cell flow passage. Each of the multiple cell capturing wells has a size that can capture one of the large cells attracted by the electrode wires.
