PROBLEM TO BE SOLVED: To provide an output circuit structure of a power supply device, capable of suppressing leakage inductance generated in an output circuit of a power supply device equipped with a transformer. SOLUTION: A primary side circuit of a transformer 4 comprises a primary winding 5, capacitors 101, 102, and switching elements 103, 104 and the like. An output circuit 1 as a secondary side circuit of the transformer 4 comprises a secondary winding 6, a choke coil 15, rectifier diodes 7, 8 and a smoothing capacitor 16 and the like. In the output circuit 1, a conductive mechanical bar 2 for connecting the cathodes of the rectifier diodes 7, 8 differently from a line made of a circuit pattern for connecting the cathodes of the rectifier diodes 7, 8. An output rectifier loop is equivalently configured as a parallel circuit, and thus, the composite impedance is reduced to suppress the leakage inductance. COPYRIGHT: (C)2008,JPO&INPIT
