To provide a bent flow passage forming member capable of suppressing flexion of a pipe body and capable of easily supporting a pipe body.SOLUTION: A bent flow passage forming member 12 constitutes an apex portion of a drain path between a drain port 1a of an air conditioner 1 and a drain pipe end portion 4a positioned above the drain port 1a. The bent flow passage forming member 12 comprises: a first pipe body side connection port 12b to which a first pipe body 10 connecting with the drain port 1a is connected; a second pipe body side connection port 12c to which a second pipe body 11 connecting with the drain pipe end portion 4a is connected; and a fixing portion 12e capable of being fixed to a support body 3 such as a structure. The first pipe body side connection port 12b and the second pipe body side connection port 12c are provided in a state where a direction 12x of the first pipe body side connection port 12b is a vertically downward direction, so that a direction 12y of the second pipe body side connection port 12c is a horizontal direction or obliquely downward direction.SELECTED DRAWING: Figure 4
