A cell response measuring device for measuring a cell response to a drug and a chip for the same are provided. A microelectrode capable of measuring a change in the electrical state of only one cell placed on a chip, a non-cell-adhesive wall covering the periphery of the electrode so that the cell is positioned on the microelectrode, A layer filled with a cell culture solution, a means for refluxing the cell culture solution and adding a drug as necessary, an annular reference electrode positioned above the microelectrode, and the microelectrode and the comparison electrode A cell response measuring apparatus comprising: means for measuring and recording a cell potential using a light; and means for optically measuring the state of one cell placed on a chip.
