In a pump device, there are formed a wall part surrounding a circuit board and a substrate contacting surface, which contacts a lower surface of the circuit board in order to locate circuit board, in a pump case. In the wall part, there is shaped a cutout part that is cut out downward from an upper end surface of the wall part, and meanwhile a leading wire, whose one end side is soldered to the circuit board, passes through the cutout part in such a way as to be drawn out to an outer side of the wall part. In the pump device, a cutout bottom part, which is a lower end part of the cutout part, and the leading wire do not contact each other so as to be detached from each other.
