An electronic component according to the present invention includes: a leadout electrode portion provided on an outer surface of an element main body; and a resin electrode layer formed at a part of the outer surface of the element main body and connected to the leadout electrode portion. The leadout electrode portion contains copper as a main component, and the resin electrode layer includes a conductor powder containing silver, and a resin. Further, a diffusion layer containing copper oxide and silver is formed at an interface between the leadout electrode portion and the resin electrode layer.

Electronic component

A coil device includes a conductor and a terminal electrode. The conductor is embedded in a core body and wound in a coil shape. The terminal electrode is formed on an end surface of the core body and connected with a lead end of the conductor. The coil device further includes a dummy conductor embedded in the core body separately from the conductor. An end part of the dummy conductor exposed from the end surface of the core body separately from the lead end is connected with the terminal electrode.
