PURPOSE: To provide a laminated coil capable of obtaining a stable inductance value without causing magnetic saturation even if a large current is supplied.
CONSTITUTION: The laminated coil 10 is provided in an independent land 10C magnetic path comprising a non magnetic metal insulated from a conductor pattern forming a coil 10A. Accordingly, the magnetic permeability in the independent land 10C is lowered to stiffen the magnetoresistance so that the total magnetic eluctance of the laminated coil 10 itself may be stiffened to decrease magnetic flux numbers hardly causing saturation even in the state that a large current flows through the coil 10A, thereby enabling a stable inductance value to be obtained without causing the decline in the inductance.
