PURPOSE:To prevent a core and a coil from being vibrated by a method wherein the coil is wound on the core at a totally strong close contact force without applying a strong stress to corner parts of the core in which electromagnetic steel plates have been laminated and without producing a gap. CONSTITUTION:An electromagnetic apparatus is formed so as to contain an upper-side part 3A and a lower-side part 3B which are formed so as to wind and laminate electromagnetic steel plates 2 and whose cross section is nearly semicircular. An insulating component 4 is formed of a flexible material. A coil 5 is wound on a core 1 via the insulating component so as to come into close contact. Thereby, it is possible to prevent the core 1 and the coil 5 from being vibrated. |
