PROBLEM TO BE SOLVED: To provide a multilayered inductor having DC superposition characteristics, where variations in inductance are small in a low-current region. SOLUTION: In the multilayered inductor, an electrically insulated magnetic layer 40 and a conductor pattern 20 are stacked, and the conductor pattern 20 of each layer is successively connected between layers, thus forming a coil turning in a peripheral direction helically while being superposed in a lamination direction in a magnetic body 41. The magnetic layer 40 forms a loop-like non-magnetic pattern 45 at a corresponding position of the conductor pattern 20, and interposes a magnetic gap 51 between magnetic circuits Hr in a laminar surface direction formed along the outer periphery of the loop-like non-magnetic pattern 45.
