发明名称 ELECTRONIC COMPONENT
摘要 An electronic component that prevents or minimizes whiskers or has good solder wettability includes a rectangular solid-shaped electronic component element and external electrodes of terminal electrodes provided at opposed end surfaces of the electronic component element. First plated films including Ni are provided on the surfaces of the external electrodes. Second plated films including Sn defining an outermost layer are arranged so as to cover the first plated films. The second plated films have a polycrystalline structure, and flake-shaped Sn—Ni alloy grains are provided at a Sn crystal grain boundary. Intermetallic compound layers including Ni3Sn4 are provided at interfaces between the first plated films and the second plated films.
