  "textContent": "There is provided a non-contact power feeding apparatus which transmits, by at least magnetic coupling, an electric power in a non-contact manner to a power reception coil from a power transmission coil electrically connected to an alternating-current power source and which outputs an electric power to a load electrically connected to the power reception coil. The non-contact power feeding apparatus includes: a coupling state estimator configured to estimate a coupling state between the power transmission coil and the power reception coil; and an available output power calculator configured to calculate an available output power that can be output to the load, based on a limit value of a circuit element of a power feeding circuit including the power transmission coil and the power reception coil and on the coupling state.",
