Abstract:
A leakage current on a side surface of a sensor chip of a cell electrophysiological sensor is reduced. In order to do so, a sensor chip having a continuity hole and a chip holding part covering the side surface of the sensor chip are provided. The sensor chip includes silicon as a main component, and the chip holding part is made of glass. The chip holding part is adhesively bonded to the side surface of the sensor chip by glass welding. Thus, in the cell electrophysiological sensor device of the present invention, the airtightness between the side surface of the sensor chip and the chip holding part is improved, so that a leakage current can be reduced.
