Abstract
A chip for a cell electrophysiological sensor has a substrate. The substrate has a through-hole formed from the upside to the downside, and the opening of the through-hole is formed in a curved surface curved from the upside and downside of the substrate toward the inner side of the through-hole. In this configuration, the electrolyte solution (first electrolyte solution and second electrolyte solution) flows more smoothly, and the sample cell can be sucked accurately, and the trapping rate of the sample cells is improved.
