摘要： PROBLEM TO BE SOLVED: To suppress axial deformation of a magnetic core leg by providing a deformation suppressing member.
SOLUTION: In a coil device, the deformation suppressing member 46 formed of a nonmagnetic material is arranged between a bobbin 40 and a coil 44 so that an upper-end part may abut against an upper block core 32 and that a lower-end part may abut against the inside of a lower block 36. When an AC current is applied to the coil 44, magnetostriction of magnetic cores and attraction and repulsion between the magnetic cores cause vibration as the current varies, but the deformation suppressing member 46 suppresses axial shrinkage of the magnetic core leg 31. Consequently, noise which may be generated accompanying the axial vibration of the magnetic leg 31 can be suppressed.
