The invention belongs to the field of mechanical pumps, and discloses a pump body and bearing integrated ultra-thin micro pump which comprises an impeller, an upper cover, a base, balls and a motor stator, wherein the impeller comprises a hub and blades distributed in the ring-shaped direction; spherical grooves are formed in the hub of the impeller; the upper cover is provided with a fluid working cavity I, a ring-shaped groove I and a sealing ring groove; the base is provided with a fluid working cavity II, a ring-shaped groove II and a motor groove; and the balls are positioned between thespherical grooves in the hub of the impeller and the ring-shaped grooves of the base and the upper cover, and used for supporting the impeller and reducing the rotating friction of the impeller. According to the pump body and bearing integrated ultra-thin micro pump, a pump body and the impeller serve as part of a ball bearing, so that the thickness of the bearing structure can be reduced; and meanwhile, no connector is n
