Original Abstract Submitted

A multilayer inductor includes a body. The body includes, within a magnetic member having a stack of magnetic layers containing iron powder, a coil including a coil conductor wound around and a through conductor that is electrically connected to the coil conductor and exposed in a bottom surface of the magnetic member. The multilayer inductor also includes an outer electrode that is on the through conductor and is electrically connected to the through conductor; and an exterior resin layer on the bottom surface of the magnetic member. The outer electrode includes protrusions that protrude perpendicular to a stacking direction of the magnetic layers in an upper end portion on a far side from the through conductor and a lower end portion on a near side from the through conductor in the stacking direction. The exterior resin layer extends across between the protrusions in the upper and lower end portions.
