PROBLEM TO BE SOLVED: To provide a non-contact power transmission device capable of approaching the power value inputted to a load suitably to a target value, and to provide a power transmission apparatus and a power reception apparatus.SOLUTION: A non-contact power transmission device 10 includes a power transmission apparatus 11 having an AC power supply 12 outputting an AC power and a primary coil 13a to which the AC power is inputted, and a power reception apparatus 21 having a secondary coil 23a capable of receiving the AC power inputted to the primary coil 13a in non-contact, and a battery 22 for vehicle. The non-contact power transmission device 10 includes a secondary measurement unit 25 for measuring the actual reception power value P2, i.e., the power value of AC power received by the secondary coil 23a, and a power supply controller 15 for controlling the transmission power value P1, i.e., the power value of AC power outputted from the AC power supply 12, based on the measurement results from the secondary measurement unit 25. |
