Zusammenfassung:	A printed circuit board (10) mounted with a power module (20) having both a plurality of lead terminals (21) for soldering and at least one screw terminal (22) for screwing includes a through hole (1) which receives the lead terminal (21) and is soldered to the lead terminal (21), and an electrode section (3) provided with a screw hole (4) fastened to the screw terminal (22) via a screw (23). A groove (6) is formed between the electrode section (3) and the through hole (1) so as to intersect with two common tangents (11 a, 11 b) each connecting, to an outer periphery of a land (2) of the through hole (1), an outer periphery of a contact area (5) of the electrode section (3) which is in contact with a head bearing surface (23c) of a screw (23) or a washer (23d).
