ABSTRACT:
A cell electro-physiological sensor includes a sensor chip including a partition board having a first surface and a second surface opposite to the first surface, a member for forming a first region provided on the first surface of the partition board, and a member for forming a second region provided on the second surface of the partition board. The partition board has a through-hole provided therein, the through-hole having a first opening which opens to the first surface, a second opening which opens to the second surface, and a wall. The first region contacts the first opening of the through-hole. The first region is arranged to contain cell suspension. The atomic ratio of carbon at the first surface of the partition board is not greater than 15 atomic percent of the composition of the first surface. The cell electro-physiological sensor causes the cell to be tightly held at the first opening of the through-hole in the partition board, thereby measuring a potential of the cell efficiently.
