In an in-tank type motor-operated pump, a pair of electric-noise suppressors (20) are contained in a pair of holes (22e) formed in a bracket (22) which holds brushes (4) and a rotor shaft (5), thereby incorporating the electric-noise suppressors in a body of the pump with the shortest connection wirings and without substantial increase of overall volume of the pump.
