An electronic component includes a lead wire, a functional element, and an outer housing. The lead wire includes a leader electrode made of metal containing aluminum, a metal wire containing tin, and a welded section formed by welding a first end of the metal wire to a first end of the leader electrode. A second end of the leader electrode is connected to the functional element. The outer housing seals the functional element therein such that a second end of the metal wire is led out therefrom. The lead wire further includes a resin film coating the welded section at least at a portion not covered with the outer housing. Resin material for the resin film has pierce strength of 0.05 MPa/&#x3bc;m per unit thickness or greater and an elastic coefficient of 10 GPa or less.

Electronic component and lead-wire for the same

A lead-wire includes a led-out electrode made of metal and a cap. The cap is put over an end of the led-out electrodes, and is made of metal harder than the metal forming the led-out electrodes. An electronic component includes a functional element and the lead-wire. The led-out electrodes is led out of the functional element.
