This wireless charging device is configured such that after charging of a portable terminal by a charging coil (8) is completed, a controller (10) drives motors (28, 33) to move the charging coil (8) to a position where the center of the charging coil deviates from the centers of multiple position detection coils (14Ba, 14Bb, 14Bc, 14Bd). As a result, echo signals from the charging coil (8) produced from pulse signals from the position detection coils (14Ba, 14Bb, 14Bc, 14Bd) become sufficiently weakened to less than a determination level, so erroneous operations can be prevented.
