Zusammenfassung:	Provided is a flow channel switching valve that has a simple structure and is easy to assemble, and thus can reduce the component cost or assembly cost. A lower valve element portion 24 provided on a valve element 20 on the opposite side of a stepping motor 50 forming a vertical movement drive unit is formed to have a smaller diameter than that of an upper valve orifice 17 and a lower valve orifice 19, and can be inserted into the inside of the lower valve orifice 19 (with a gap of a predetermined size) via the upper valve orifice 17, and thus the valve element 20 can be inserted into the valve chamber 11 and disposed in a predetermined position within the valve chamber 11 (in one direction) from the upper side of the valve body 10.
