PROBLEM TO BE SOLVED: To provide an electronic component for which mechanical connection strength between an extraction electrode and a metal wire is secured, drop of a whisker to a board is prevented, and impact resistance, vibration resistance and short-circuiting resistance are improved. SOLUTION: The electronic component comprises a capacitive element 16, and lead wires 11 connected to the capacitive element 16, and is structured such that the lead wire 11 comprises a metallic extraction electrode 12 connected to one end of the capacitive element 16, a metal wire 13 harder than a material of the extraction electrode 12, and having one end 13a embedded in the other end 12b of the extraction electrode 12, and a flange part 15 formed between the one end 13a and the other end 13b of the metal wire 13; interfaces of the extraction electrode 12 and the embedded metal wire 13 are welded to each other to form an alloy layer 14; and the flange part 15 is arranged to cover an exposed part 14a where the alloy layer 14 is exposed from the other end 12b of the extraction electrode 12.
