Abstract: Provided is a measurement device including a mounting unit in which a flow channel device is attachably and detachably mounted, the flow channel device including a first flow channel, a second flow channel having a communicating portion that communicates with a part of the first flow channel, and a cell sheet in which a plurality of cultured cells are arranged in such a manner that the cells are bound to each other and which partitions between the first flow channel and the second flow channel at the communicating portion; and a detection unit that optically distinguishes and detects a leakage state of each of a plurality of types of tracers having different sizes and leaking out from the first flow channel into the second flow channel through a defect occurring in the cell sheet in a case where an evaluation liquid is fed into the first flow channel.
