PURPOSE:To reduce the size of an induction type laminated coil and to readily manufacture the coil by symmetrically forming a conductor pattern to form two coils in a laminating step. CONSTITUTION:Rectangular ferrite magnetic layer 1 is printed or attached to the suitable planar plate, concentric circles 2, 3 and 2', 3' symmetrical with respect to the central vertical line are traced in a coil to print the conductor, and two conductive coils are formed. External terminal paste is coated on the leads a, b exposed at the left and right sides, and external terminals are provided. The completed coil has an inductance formed of left and right side conductors and an inductance produced by the induction between the conductors. |
