Abstract
An electronic component includes an insulating base material including insulating base material layers, a first main surface that is a mounting surface, a coil, mounting electrodes provided on the first main surface, and a projection. The coil includes coil conductors provided on the insulating base material layers and a winding axis in a laminating direction of the insulating base material layers. The projection is provided in an electrode non-forming portion of the first main surface, the electrode non-forming portion including no mounting electrodes therein, and provided along the coil conductors in planar view of the first main surface.
