PROBLEM TO BE SOLVED: To ideally transmit the bending moment which is generated in a laminated yoke body during operation, by forming two mutually coupled parallel partial bodies forming the yoke body of many narrow, and long piece plates respectively having U-shaped cross sections and fitted to each other by bending the plates in U-shapes. SOLUTION: A yoke body 1 is formed of two mutually coupled parallel partial bodies 6 and 7. Each partial body 6 and 7 is formed of many narrow and long bent U-shaped piece plates 8 which are fitted to each other as one assembly. The plates 8 are firmly fixed to each other by bonding, welding, or soldering. The partial bodies 6 and 7 are also coupled with each other in one rigid body by bonding or soldering. Alternatively, the partial bodies 6 and 7 are collectively held in an integral state in a housing. Therefore, the magnetic characteristic of the yoke body 1 can be optimized by ideally transmitting the bending moment generated during operation.
