Abstract
A flow path switching device includes a fixed member and a driven member and drives the driven member to switch between combinations of ports of the fixed member and communication paths of the driven member to be communicated to switch a flow path. The flow path switching device has a seal member provided protruding toward the fixed member near the communication path of the driven member to seal a part between the driven member and the fixed member, and a control unit that controls driving of the driven member. When switching the flow path, the control unit performs additional drive control in which the driven member is further driven from a prescribed stop position after switching of the flow path and then performs return drive control in which the driven member is returned toward the prescribed stop position.
