Abstract
A measurement deviceincludes a measurement cell. The measurement cellincludes a substratesand a substrateformed on the substrate. The substratesandare bonded to each other. Thus, a flow passis formed in the measurement cell. As shown in FIG., on the substrateof the measurement cell, provided are a concave well, a protruding microelectrodeconnected to a terminaland formed on a side wall surface of the well, communicating tubesandconnected to both of side surfaces of the well(i.e., the flow pass) to face to each other, resistance bathsandconnected to the communicating tubesand, thin film resistorsandarranged in the resistance bathsand, and a reference electrodeconnected to a terminal
