Liquid tank formation method, measurement device, and analysis device

A measurement device comprising:

• a substrate with a membrane in which the membrane is provided to close an opening;
• a substrate with an independent electrode in which the independent electrode is provided;
• a partition wall that forms a compartment including the independent electrode between the substrate with the membrane and the substrate with the independent electrode;
• a first stage that is connected to the substrate with the membrane;
• a second stage that is connected to the substrate with the independent electrode;
• a mechanism that aligns the substrate with the membrane and the substrate with the independent electrode;
• a driver that brings the first stage and the second stage close to each other and presses the substrate with the membrane and the substrate with the independent electrode through the partition wall;
• a power supply for applying a voltage between an electrode disposed opposite to the independent electrode through the membrane and the independent electrode;
• and
• a measurement unit that measures a current flowing through the independent electrode by applying a voltage from the power supply.

An analysis device comprising:

• a substrate with a membrane in which the membrane is provided to close a plurality of openings disposed in an array;
• a substrate with independent electrodes in which a plurality of the independent electrodes are provided in an array;
• and
• a partition wall that forms a plurality of compartments each including each of the independent electrodes between the substrate with the membrane and the substrate with the independent electrodes, wherein
• a plurality of liquid tanks filled with a solution are configured by the substrate with the membrane, the substrate with the independent electrodes and the partition wall, the plurality of the independent electrodes are substantially insulated by separation of the solution by the partition wall, and each of the liquid tanks has no flow path and the solution is sealed in each of the liquid tanks.
