  "textContent": "In a wireless power transfer apparatus, a characteristic adjuster has a frequency characteristic that causes, in a power transfer mode from at least one power transmission unit to a power receiving apparatus, a resonant power transmission circuit to have a resonance frequency that substantially matches an operating frequency. The reactance of a power transmission coil has a reference value in the power transfer mode. The frequency characteristic of the characteristic adjuster causes, in a power non-transfer mode from the at least one power transmission unit to the power receiving apparatus, a reactance of a power transmission coil to become an adjusted value that is higher than the reference value.",
