When an electrode component is inserted into a through hole from one side and then rotated, parts of a conductive film are cut by a cutting blade Another electrode component including a chip component whose one terminal is connected to an electrode of this electrode component is inserted into the through hole from the other side. When compression bonding is applied to the both electrode components so as to be joined together, an electrode of the former electrode component and the electrode of the latter electrode component are spread within the through hole with the pressure. The spread electrode of the former electrode component contacts a portion of the conductive film that is electrically connected to a front surface wiring, and tho spread electrode of the latter electrode component contacts another portion of the conductive film that is electrically connected to a back surface wiring.
