A viscous material () is obtained by mixing an alloy magnetic powder, magnetized in advance, with a resin. The viscous material () thus obtained is applied to an upper surface of a center magnetic leg of an E-shaped core (). A coil () and an I-shaped core are coupled to the E-shaped core (). An orientation magnetic field is applied by a permanent magnet () while the resin is hardened. As a consequence, a bond magnet is obtained which is formed in tight contact with both of a pair of surfaces defining a magnetic gap between the E-shaped core () and the I-shaped core.
