PROBLEM TO BE SOLVED: To provide a motor-integrated internal gear pump and electronic equipment in which an inexpensive and miniaturized pump is provided, and a high degree of reliability is ensured, while maintaining the inexpensive function. SOLUTION: The motor-integrated internal gear pump 80 comprises a pump part 81 for sucking and discharging hydraulic fluid, and a motor part 82 for driving the pump part 81. The pump part 81 comprises an internal rotor 1 with teeth formed on the outside periphery, an external rotor 2 with teeth formed on the inside periphery to be meshed with the teeth of the internal rotor 1, and pump casings 3, 4 for enclosing the internal rotor 1 and the external rotor 2. The motor part 82 comprises a rotor 11 and a stator 12 for rotating the rotor 11. The rotor 11 and the external rotor 2 are formed by sharing a permanent magnet member 112 prepared by adding magnetic powder in a resin. COPYRIGHT: (C)2007,JPO&INPIT
