A composite magnetic material used for a choke coil is formed by compression molding of a mixture of magnetic alloy powder with a base of iron and nickel; an insulating material; and a binder consisting of silicone or acrylic resin. The composite magnetic material has a high filling rate of magnetic alloy powder, high dielectric property, low core loss and high permeability. This magnetic material can be formed into a complex shape. |
