PURPOSE: To provide an inexpensive non-contact type DC power unit which is used for electronic equipment, has a small size, and can transmit a larger amount of electric power. CONSTITUTION: In a non-contact type DC power unit in which a primary coil 11 supplied with a pulse-like current and a secondary coil 13 housed in an enclosure which is different from that housing the coil 11 are faced to each other and electric power is transmitted to the secondary coil 13 from the primary coil 11, a ferrite core 12 which is extended to the secondary coil 13 from the primary coil 11 is provided so that the electric power can be transmitted efficiently to the coil 13 from the coil 11. |
