Summary:PROBLEM TO BE SOLVED: To provide a core assembly, wherein eddy currents are suppressed to a minimum, while a bush for supporting reciprocating axis is housed. SOLUTION: A core assembly 20 comprises a large number of laminating plates 28 laminated along a lamination axis line A, the laminating plates have almost the same thickness B, the core assembly 20 comprises an integral core member 30, the core member is provided almost at the center of the many laminating plates 28, each end part 31 and 33 of the core member makes contact with a single laminating plate respectively, the core member has a thickness C significantly thicker than the thickness B of the laminating plate, and the core member 30 comprises an opening 32 so allocated, in the direction almost vertical to the laminating axis line A, as to penetrate the core member.
