PROBLEM TO BE SOLVED: To prevent a liquid after being exchanged from mixing with another liquid when exchanging the liquids. SOLUTION: A flow path selector device 100 comprises a valve sheet member 110 (a first member) having a plurality of flow-in paths 112 (the first flow paths) for passing the liquids, a revolving valve 120 (a second member) disposed revolvably to the valve sheet member 110 and movably in the revolving axis direction, and having a flow-out path 121 (a second flow path) for passing the liquids by communicating with any of a plurality of the flow-in paths 112, and a driving part 130 for moving the revolving valve 120, wherein the revolving valve 120 is disposed at a communicating position selectively communicating with the flow-out path 121 and any of a plurality of the flow-in paths 112 according to its revolved position, and at a closing position closing a plurality of the flow-in paths 112 by moving in the revolving axis direction to the valve sheet member 110.
