Summary:There is provided a flow passage switching valve that can individually perform the flow control of flow passages of a system including a plurality of flow passages while reducing the number of parts. A first flow passage in which a first inlet and a first outlet formed at a valve body communicate with each other through communication holes of a cylindrical valve element portion of a valve element and a second flow passage in which a second inlet and a second outlet communicate with each other through the communication holes of the cylindrical valve element portion are switched according to a change of a rotational position of the valve element.
