Abstract: In an electronic component, a plurality of conductor layers extend in a direction that intersects a coil axis and that is along insulator layers. Each of the plurality of connection conductors is connected to a corresponding conductor layer among the plurality of conductor layers, and extends in a stacking direction. In the conductor layers adjacent to each other in a direction along the coil axis among the plurality of conductor layers, a width in a direction orthogonal to an extending direction of each of the conductor layers is larger than a shortest distance between the conductor layers adjacent to each other. An extending direction of each of first conductor layers and an extending direction of at least one second conductor layer intersect each other when viewed in the stacking direction, and are inclined to a direction that is orthogonal to the coil axis and that is along the insulator layers.
