To provide a non-contact charging control device capable of preventing increase in a leakage magnetic field during power supply.SOLUTION: A non-contact charging system 1 charges a vehicle 10 that is stopped or passing through directly above a non-contact charging device 20 by supplying power (feeding power) to the vehicle 10 in a non-contact manner. The non-contact charging control device 20 includes: a transmission unit having a power transmission coil (a ground side coil 23) for supplying power in a non-contact manner toward a power receiving coil (a vehicle side 11) provided in the vehicle 10; a current detection unit 24 for detecting a current value supplied to the transmission unit; and a control unit 25 for determining whether or not an amount of change in a current value exceeds a preset threshold value and stopping power supply by the power transmission coil when the amount of change in the current value exceeds the threshold value.SELECTED DRAWING: Figure 1 【課題】給電時に漏洩磁界が増大することを防止することができる非接触充電制御装置を提供する。【解決手段】非接触充電装置２０の直上に停車または通過する車両１０に向けて非接触によって電力を送電（給電）することによって車両１０を充電する非接触充電システム１において、非接触充電制御装置２０は、車両１０に設けられた受電コイル（車両側１１）に向けて非接触で電力を給電する送電コイル（地上側コイル２３）を有する送信部と、送信部へ供給される電流値を検出する電流検出部２４と、電流値の変化量が予め設定された閾値を超えたか否かを判定し、電流値の変化量が閾値を超えた場合、送電コイルによる電力の給電を停止する制御部２５と、を備える。【選択図】図１
