Abstract: Provided is an electronic component capable of reducing a possibility that insulating layers covering from outer edge portions of electrodes to surrounding portions, around the electrodes, of a substrate are separated from the electrodes and the substrate. An electronic component includes: a substrate; an electrode formed on a surface of the substrate; a protective portion covering at least a part of a peripheral portion of the electrode and a surrounding portion, around the electrode, of the surface of the substrate, across outer edge portions of the electrode, and extending in a circumferential direction along the outer edge portions of the electrode; and an extending portion extending, on the surface of the substrate, from the protective portion in an extending direction away from the electrode. A width of the extending portion perpendicular to the extending direction is longer than a width of the protective portion perpendicular to the circumferential direction.
