Abstract: A flexible inductor includes a coil substrate having a first spiral conductor formed in or on a bottom surface, a first magnetic sheet laminated on a top surface of the coil substrate, and a second magnetic sheet laminated on the bottom surface of the coil substrate. The flexible inductor includes a plurality of outer electrodes including a first outer electrode and a second outer electrode that are disposed in a peripheral portion of the bottom surface of the coil substrate, and cutout portions each formed in an area between the first spiral conductor and each of the outer electrodes so as to penetrate through the coil substrate. The first outer electrode is electrically connected to an outermost end portion of the first spiral conductor. The second outer electrode is electrically connected to an innermost end portion of the first spiral conductor.

Abstract: A coil component including an element assembly that includes a magnetic portion and a coil-like conductor portion embedded in the magnetic portion and outer electrodes disposed on an outer surface of the element assembly, wherein the outer surface has a mounting surface parallel to the central axis of a coil, the magnetic portion includes a first portion, a second portion, and a third portion, the first portion and the third portion contain glass and ferrite and have ferrite contents of 40 percent by volume or more, the second portion contains glass and ferrite and has a ferrite content smaller than the ferrite contents in the first portion and the third portion, and each of the first portion and the third portion has a covered region that is covered with the outer electrode and an exposed region that is not covered with the outer electrode on the mounting surface.
