Abstract
A laminated ceramic capacitor includes a rectangular solid-shaped electronic component element. External electrodes of terminal electrodes are disposed at one end surface and the other end surface of the electronic component element. First plated films including a Ni plating are disposed on the surfaces of external electrodes. On the surfaces of the first plated films, second plated films containing Sn are disposed as Sn-plated films defining outermost layers of the external electrodes. The second plated films have a polycrystalline structure, and flake-shaped Sn—Ni alloy grains are located at a Sn crystal grain boundary and within a Sn crystal grain, respectively.
