PURPOSE:To reduce sharply magnetic flux to flow into the tank of an induction apparatus, and to suppress loss to the minimum by a method wherein second magnetic shields adhered closely to first magnetic shields and having the large different fitting direction therefrom are arranged on the upper surfaces of the first magnetic shields equipped to the tank. CONSTITUTION:Second magnetic shields 6 are arranged on the upper surfaces of first magnetic shields 4 adhering closely thereto, and changing the fitting direction large (at 90 deg.). According to this construction, because magnetic flux is enabled to advance to the original direction of leakage magnetic flux passing the magnetic bodies 4a, 6a of the longitudinal and lateral directions, magnetic flux to pass through a tank 1 having an inferior magnetic loss characteristic is reduced sharply, and loss generated in the tank 1 can be made to the minimum. |
