Abstract
Abstract In the inventive electronic parts, external leads are installed at a board on which a multilayer capacitor is mounted, external leads being electrically connected with terminal electrodes of the capacitor through conductors which are provided on the board. And therefore it is possible to easily fabricate the capacitor into an electric device in three-dimensions through the external leads.
