PROBLEM TO BE SOLVED: To provide a non-contact charging system that can prevent erroneous display of a direction leading to an optimal position to charge a device to be charged.SOLUTION: A power transmission device 2 of a non-contact charging system 1 comprises: a power transmission control unit 11 that detects the position of a mobile terminal 3 placed on a placement surface and determines a direction to lead to an optimal position optimal to charge the mobile terminal 3 from the detected detection position; a power transmission side communication unit 15 that transmits an instruction direction signal indicating the direction determined by the power transmission control unit 11 to the mobile terminal 3. The mobile terminal 3 comprises: a mobile side communication unit 25 that receives the instruction direction signal transmitted by the power transmission side communication unit 15; a display unit 5 able to display an arrow; and a display control unit 26 that performs control on the basis of the instruction direction signal such that an arrow displayed by the display unit 5 accords with a real direction toward the optimal position from the detection point viewed from the power transmission device 2 as a reference. |
