Abstract
A noncontact charging device includes a mounting portion, a primary transmission coil, a temperature-detecting element, and a control unit. A device charged in a noncontact manner is mounted on the mounting portion. The primary transmission coil supplies power to a secondary transmission coil provided to the device by the use of electromagnetic induction. The temperature-detecting element detects a temperature of a material mounted on the mounting portion. The control unit is configured to supply power to the primary transmission coil and terminate the power supply to the primary transmission coil when a predetermined temperature is detected by the temperature-detecting element. The temperature-detecting element is located on a side of a contact surface between the mounting portion and the primary transmission coil, and the center of the temperature-detecting element is located within a range of the diameter of the primary transmission coil from the center position of the primary transmission coil.
