Abstract:
An electronic component includes an element body, an external electrode, and a metal terminal. In the metal terminal, a base includes a first surface and a second surface opposing each other, and a pair of third surfaces coupling the first surface and the second surface. A first metal layer is disposed on the first surface and connected to solder with which the external electrode and the metal terminal are connected together. A second metal layer is disposed on the second surface. A coating layer is disposed on each of the third surfaces. The first metal layer and the second metal layer each include an outermost layer containing Sn. Each of the coating layer includes an outermost layer lower in solder wettability than the respective outermost layers of the first metal layer and the second metal layer.
