Abstract This power supply device (2), which supplies electric power in a non-contact manner to a power-receiving device (4), is provided with: a substrate (42); a primary coil (44) that is positioned on the substrate (42), and generates flux by means of an alternating current; a cover (40) that is attached to the substrate (42), and covers the primary coil (44); and a capacitance sensor (14) that detects an object that is present on the cover (40). Since the capacitance sensor (14), which is capable of detecting the object that is present on the cover (40), is provided, a foreign object between the primary coil (44) and a secondary coil belonging to the power-receiving device (4) can be reliably detected. L'invention concerne un dispositif d'alimentation en énergie (2), qui fournit une énergie électrique d'une manière sans contact à un dispositif de réception d'énergie (4), qui comprend : un substrat (42) ; une bobine primaire (44) qui est positionnée sur le substrat (42) et génère un flux au moyen d'un courant alternatif ; une couverture (40) qui est fixée au substrat (42) et recouvre la bobine primaire (44) ; et un capteur de capacitance (14) qui détecte un objet qui est présent sur la couverture (40). Etant donné que le capteur de capacitance (14), qui est apte à détecter l'objet qui est présent sur la couverture (40), est présent, un objet étranger entre la bobine primaire (44) et une bobine secondaire appartenant au dispositif de réception d'énergie (4) peut être détecté de façon fiable.
