Abstract
A ferrite bead inductor comprises a ferrite bead element body having magnetic layers and inner electrodes stacked therein, and first and second outer electrodes arranged on first and second side faces of the ferrite bead element body. The inner electrode extends in the direction of shorter sides which are shorter than longer sides, so as to connect with the first and second outer electrodes. The ferrite bead element body has an interstice for allowing the magnetic layers adjacent to each other in the stacking direction to join together within an inner electrode region adapted to form the inner electrode on the magnetic layer.
