PROBLEM TO BE SOLVED: To suppress surge voltage applied to a switching element, in a multiple output insulation converter, which distributes the power obtained from a DC power source via a transformer by turning on/off the switching element to a plurality of loads via a coil. SOLUTION: The multiple output insulation converter 1 comprises a transformer 33 connected to the DC power source 32 at one end of a primary-side coil 31, a switching element 35 connected to the other end of the primary-side coil 31, an output terminal 39 connected to the secondary-side coil 36 of the transformer 33 via a diode 37 and capacitor 38, a coil 54 of the insulation-type converter 53, connected to the secondary-side coil 40 of the transformer 33, and a current-suppressing element 2 provided between the secondary-side coil 40 and the coil 54 and constituting a differential circuit, together with the coil 54.
