Abstract:
A chip-shaped electronic part includes: a substrate; a pair of upper surface electrodes formed on an upper surface of the substrate; a functional element formed to be electrically connected to the upper surface electrode pair; a pair of lower surface electrodes formed on a lower surface of the substrate at positions opposing the upper surface electrode pair; a pair of end surface electrodes formed on end surfaces of the substrate so that each of the end surface electrode pair is electrically connected to one of the upper surface electrode pair, and to one of the lower surface electrode pair corresponding to the one upper surface electrode; a protective film formed in such a manner as to cover at least the functional element; and a plated layer formed in such a manner as to cover at least each of the upper surface electrode pair, wherein the protective film or the plated layer has at least two points of application at which a load from above the substrate is exerted.
