REACTOR

This reactor comprises a coil having a pair of winding parts that are disposed in parallel via a connecting part, a magnetic core having internal core parts disposed inside each of the winding parts and a pair of external core parts disposed outside both of the winding parts, a pair of holding members disposed so as to oppose the end faces of both of the winding parts, and a mold resin part that covers at least portions of the outer peripheral surfaces of the external core parts and fills the spaces between the inner peripheral surfaces of the winding parts and the internal core parts. The coil is configured from one continuous winding. The connecting part is formed through the folding back of one portion of the winding. The holding member on the side on which the connecting part is disposed comprises a recessed part for accommodating the connecting part and an internal protrusion disposed inside the connecting part. 一种电抗器，具备：线圈，具有经由连结部而并列配置的一对卷绕部；磁芯，具有配置在各卷绕部的内侧的内侧芯部和配置在两卷绕部的外侧的一对外侧芯部；一对保持构件，以与两卷绕部的各端面相对的方式配
