ABSTRACT:
A printed circuit board which is an electrically insulative substrate of synthetic resin having at least one pair of spaced electroconductive layers. An electric and/or electronic component, such as resistor or capacitor, of a type which has no lead wires extending outwardly therefrom for external electric connection, but which is constituted by a substantially cubic body having its opposed area applied with respective films or foils of electroconductive material which serve as terminal electrodes, is mounted on the substrate with the terminal electrodes soldered to the respective electroconductive layers. To this end, each of the electroconductive layers has a round portion for connection with the associated terminal electrode of the component. Each round portion has an effective surface area equal to or smaller than any of the terminal electrodes.
