A vortex pump device may include a pump case which forms a pump chamber and a stator accommodating chamber partitioned from the pump chamber, and a wiring outlet part for taking out a wiring line within the pump case to an outer side. The pump case is provided with an outer peripheral wall surrounding an upper space formed on an upper side in the stator accommodating chamber. The wiring outlet part includes a wiring outlet port which is formed by cutting out the outer peripheral wall, a wire placing part on which the wiring line taken out from the wiring outlet port to the outer side is placed, and a fixing member with which the wiring line is sandwiched and fixed between the wire placing part.
