Beschreibung
Zusammenfassung:	This power feeding device (3) is equipped with a cover (313), a primary coil (35) covered by the cover (313), and a plurality of temperature sensing means (39) which are provided within the cover (313) and detect the temperature of an object upon the cover (313). W satisfies formula (1) when the distance between adjacent temperature sensing means (39) among the plurality of temperature sensing means (39) is W[m], the temperature of the object serving as the target of temperature detection by the temperature sensing means (39) is T0[K], the temperature which should be detected by the temperature sensing means (39) is T1[K], and the thermal conductivity of the cover (313) is Lambda [W/(m.K)]. As a result, it is possible for the power feeding device (3) to accurately detect the temperature of the object upon the cover (313).
