Abstract
A power feeding device includes a cover, a primary coil covered with the cover and provided in a predetermined direction with respect to the cover, and a temperature-sensitive detector that detects the temperature of an object on the cover. When the distance from the surface of the cover to the temperature-sensitive detector in the predetermined direction is denoted by L [m], the temperature of the object to be subjected to thermometry by the temperature-sensitive detector is denoted by T0[K], the temperature to be detected by the temperature-sensitive detector is denoted by T1[K], and the thermal conductivity of the cover is denoted by λ [W/(m·K)], L satisfies the following equation
This allows the temperature of the object on the cover to be accurately detected.
