Abstract
An electronic component includes a wire and a terminal electrode connected to a lead of the wire and at least partly covered with a deposited film. The deposited film of the terminal electrode connected to the lead includes a surface having a glossy surface with fewer surface irregularities than those of a non-glossy surface remaining as-is as of formation of the deposited film. The glossy surface is located near the lead connected to the terminal electrode.
