This non-contact power transmission device (10) comprises: a power transmitter (13) that includes a primary-side coil (13a) and a primary-side capacitor (13b) connected in parallel to one another, and to which alternating-current power is supplied; and a power receiver (23) that includes a secondary-side coil (23a) and a secondary-side capacitor (23b) connected in parallel to one another, and that is capable of receiving alternating-current power in a non-contact manner from the power transmitter (13). The non-contact power transmission device (10) comprises an impedance converter (25) provided between the power receiver (23) and a load (22). The impedance converter (25) converts impedance such that a second impedance (Z2) becomes higher than a specific impedance (Zq). |
