Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a core used in a power reception side coil unit of a vehicle non-contact charging system which enables a resin case to be thinly formed and reduces distances between magnetic material elements to improve the electric power transmission efficiency.SOLUTION: A core 40 used in a power reception side coil unit 21 of a vehicle non-contact charging system 10 includes: multiple magnetic material elements 41 which are formed into a rectangular flat plate shape and arranged in a lattice manner without forming gaps therebetween; and a resin insert core case 42 which integrally packages the multiple magnetic material elements by insert-molding the multiple magnetic material elements. 【課題】樹脂ケースを薄くすることができ、磁性体素片間の距離を小さくして電力の伝送効率を向上することができる車両用非接触充電システムの受電側コイルユニットに用いられるコアを提供する。【解決手段】車両用非接触充電システム１０の受電側コイルユニット２１に用いられるコア４０は、矩形平板形状に形成され、格子状に隙間なく配列された複数の磁性体素片４１と、複数の磁性体素片をインサート成形することにより、複数の磁性体素片を一体的に包み込む樹脂製のインサートコアケース４２と、を含む。【選択図】図２
