发明名称 電子部品及びその製造方法
摘要 An electronic component including an electronic component element with an external electrode, a Ni plating film on the external electrode, and a Sn plating film covering the Ni plating film. The Sn plating film has Sn—Ni alloy flakes therein, the Sn—Ni alloy flakes are present in the range from a surface of the Sn plating film on the Ni plating film to 50% or less of the thickness of the Sn plating film, and when Sn is removed from the Sn plating film to leave only the Sn—Ni alloy flakes, an observed planar view of a region occupied by the Sn—Ni alloy flakes falls within the range from 15% to 60% of the observed planar region.
