A smaller-sized, more lightweight, and power-saving successive magnetic pulse device is provided. A discharging circuit section K is configured by connecting, in series in a loop, a magnetic therapy pulse coil 6 configured to generate an eddy current in a target part 3, a charging/discharging capacitor 4, and a switching semiconductor element 7 configured to supply a discharge current from the charging/discharging capacitor 4 to the pulse coil 6. A step-up transformer 1 includes a primary-side coil 1a connected to an AC power supply 2 and a secondary-side coil 1b connected to input terminals 5a of a full-wave rectifying circuit 5. A control unit 8 is connected to a switching semiconductor element 7 and controls conduction timing of the switching semiconductor element 7. The full-wave rectifying circuit 5 has output terminals 5b connected to both terminals P1 and P2 of the charging/discharging capacitor 4, respectively. An inductor 9 is connected between the output terminal 5b of the full-wave rectifying circuit 5 and the terminal P1 of the charging/discharging capacitor 4. |
