An electrical pump apparatus is provided in which a situation where a failure detection circuit becomes inoperative before detection of a failure of an electric system can be avoided, and the certainty of failure detection can be enhanced. An attaching portion which is to be attached to a vehicle body is formed so that, in a state where an electrical pump apparatus is attached to the vehicle body, a circuit board of a control device is perpendicular to the horizontal direction. A control IC chip which constitutes a microcomputer for detecting a failure of the electric system is placed on a circuit board so as to be higher in the direction of gravity from a lowest water level Hmin at which flooding in a housing causes the electric system to be short-circuited. |
