Claim 0:
1. An extracellular potential measurement device comprising:
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 being interposed between an upper insulating film and a lower insulating film,
each of the insulating films, except for a lowermost insulating film, having an opening penetrating the insulating film,
the opening in a lower insulating film having 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 having 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.
