PROBLEM TO BE SOLVED: To provide a power supply device and a wireless power transmission system that suppress generation of electromagnetic interference with surrounding apparatuses other than coils transmitting/receiving to/from each other via a magnetic field.SOLUTION: A power supply device 200 comprises: a first power supply device 210 mounted on a mobile body 500; and a second power supply device 300 configured so as to be detachably attached to the mobile body 500. The first power supply device 210 includes a first coil 221 for transmitting/receiving AC power via a magnetic field. The second power supply device 300 includes: a second coil 311 for transmitting/receiving AC power to/from the outside or the first coil 221 via the magnetic field; and a power storage unit 350 for storing power received by the second coil 311 or discharging power to the second coil 311.SELECTED DRAWING: Figure 1
