Abstract:
1. A method of manufacturing a wired circuit board, comprising: forming an insulating layer in a pattern thereby forming second through holes penetrating the insulating layer in a thickness direction thereof; and after forming the insulating layer, forming, on the insulating layer, a conductive pattern in a pattern having terminals which are continuous with an upper surface and a side surface of a side end portion of the insulating layer such that the terminals extend into the second through holes, the terminals being operative for connecting with external terminals via a molten metal, the terminals including annular, step-shaped shoulder portions aligned with the second through holes and that are recessed downward from an upper surface, and first through holes having a diameter smaller than that of the second through holes and which pass through the terminals in a thickness direction thereof.
