Abstract
A reactor includes: a coil including a first winding portion and a second winding portion formed by winding a winding wire, such that axes of the winding portions are parallel; and a magnetic core including: a first inner core portion arranged in the first winding portion; a second inner core portion arranged in the second winding portion; and outer core portions that are arranged outside of the winding portions and couple both inner core portions. A specification of a constituent material of the first inner core portion and a specification of a constituent material of the second inner core portion are different, and the second inner core portion is configured such that alternating-current loss of the second inner core portion and the second winding portion is smaller than alternating-current loss of the first inner core portion and the first winding portion.
