To provide a technology of increasing effects of suppressing a parasitic inductance in a circuit module wherein a full-bridge circuit is mounted on a substrate. Disclosed is a full-bridge circuit module (1) wherein: two half-bridge circuits are mounted on one main surface of a module substrate (10); wide conductor units (11-1, 11-2) are formed in regions corresponding to the half-bridge circuits, said regions being parts of the other main surface of the module substrate; and the wide conductor units are connected to negative-side power source patterns (34-1, 34-2) via connecting electrodes (42-1, 42-2), said negative-side power source patterns functioning as negative-side power sources. |
