1. An electronic component comprising:
an element body, wiring being provided in the element body;
a terminal electrode provided on a surface of the element body and electrically connected to the wiring; and
an insulating coating layer covering the terminal electrode, wherein
the element body is made of a metal magnetic powder-containing resin and has a mounting surface facing a mounting substrate and a rectangular end surface extending in a height direction intersecting with the mounting surface,
the terminal electrode is made of a conductive resin and continuously covers the mounting surface and the end surface of the element body,
the terminal electrode is separated from all three sides other than a side corresponding to the mounting surface and a U-shaped exposed region where the end surface is exposed from the terminal electrode is formed on the end surface,
the insulating coating layer is made of a resin material and integrally covers the terminal electrode and the exposed region on the end surface, and
a thickness of the insulating coating layer on the end surface of the element body is not uniform such that a thickness of the insulating coating layer at an intermediate position along the height direction is smaller than: (i) a thickness of the insulating coating layer at a first position in between the intermediate position and the mounting surface along the height direction and (ii) a thickness of the insulating coating layer at a second position on an opposite side of the intermediate position with respect to the first position along the height direction.
