1. A multilayer inductor comprising:
an element body formed by stacking a plurality of layers of insulators in a stacking direction, the element body having a first side surface, a second side surface, a first end surface and a second end surface, the first end surface and the second end surface facing each other in a first direction and each connecting the first side surface and the second side surface, the first side surface and the second side surface opposing each other in a second direction perpendicular to the first direction;
a first terminal electrode provided on the first end surface and extending on the first side surface;
a second terminal electrode provided on the second end surface and extending on the first side surface; and
a linear conductor portion provided in the element body and extending in the first direction, the linear conductor portion having a first end connecting the first terminal electrode at the first end surface and a second end connecting the second terminal electrode at the second end surface,
wherein, as viewed from the second direction, the conductor portion has a first portion in a region overlapping the terminal electrode and a second portion in a region not overlapping the terminal electrode, and
wherein a width of the first portion as viewed from the second direction is smaller than a width of the second portion.
