Microorganism quantity measurement cell and microorganism quantity measurement device comprising same

A microorganism quantity measurement cell, comprising:

• a measurement chamber configured to measure the number of microorganisms included in a sample liquid;
• an inflow aperture through which the sample liquid flows into the measurement chamber;
• an outflow aperture through which the sample liquid flows out of the measurement chamber;
• a measurement electrode provided in the measurement chamber at a position toward the outflow aperture;
• a concentration electrode provided in the measurement chamber at a position toward the inflow aperture;
• and
• an insulator provided on the concentration electrode,
• wherein the measurement electrode is provided on a first face of the measurement chamber that is parallel to the direction in which the sample liquid flows inside the measurement chamber,
• the concentration electrode is provided on a second face of the measurement chamber that is opposite the first face and is parallel to the direction in which the sample liquid flows inside the measurement chamber, and
• an electric field concentration portion is formed in a part in which a repulsive force is produced by the insulator when concentration-use AC voltage is applied to the concentration electrode.
