ABSTRACT:
A sensing element for measuring extracellular potential including a substrate, a well provided in a substrate, a guide section provided on the wall of the well, and a detective electrode formed at a lower surface of the substrate. The guide section is for guiding drug. The well is provided at the bottom with a depression, and a first throughhole penetrating through the depression and the lower surface of the substrate. The well is for mixing a subject cell, a culture solution and the drug together. The above-configured sensing element accurately measures a change generated by a subject cell.
