PROBLEM TO BE SOLVED: To provide a magnetic force-driven pump unit which allows fluid to flow by a small amount of member. SOLUTION: A body 11 is provided with one accommodation space thereinside, wherein at least the outside is a magnetic conductive material. A block 12 has a constant length and the outer peripheral shape corresponding to the inner peripheral shape in the accommodation space, and is made freely rockable in the accommodation space and driven by magnetic force. The coil 13 is wound around the outer peripheral surface of the body 11 and connected with an electronic circuit for supplying current, and drives the block 12. By driving the block 12, fluid disposed on one side or both sides of the block 12 can be fluidized. COPYRIGHT: (C)2007,JPO&INPIT
