PROBLEM TO BE SOLVED: To provide a non-contact power transmission device that allows preventing the flow of an excessive current through a primary-side coil due to the change in relative position of each coil.SOLUTION: A non-contact power transmission device 10 includes: a power transmitter 13 having a primary-side coil 13a and a primary-side capacitor 13b that are connected in parallel to each other, and receiving AC power; and a power receiver 23 having a secondary-side coil 23a and a secondary-side capacitor 23b that are connected in parallel to each other, and capable of receiving AC power from the power transmitter 13 in a non-contact manner. The non-contact power transmission device 10 further includes an impedance converter 25 provided between the power receiver 23 and a load 22, and the impedance converter 25 performs impedance conversion so that second impedance Z2 is higher than specific impedance Zq. |
