Abstract
A magnetic device of smaller size and lower profile comprising a coil conductor of high inductance and low resistance is provided. The magnetic device comprises a coil conductor and a multilayer magnetic layer formed so as to cover the periphery of the coil conductor. Further, a magnetic device having higher inductance value and lower conductor resistance value (AC resistance) by selecting a magnetic layer capable of suppressing the eddy current and having excellent magnetic characteristics even designed with smaller size and lower profile.
