Abstract
The present invention has an object of providing a reactor including cores with higher heat dissipation and a coil with less eddy-current loss. A reactor according to the present invention includes: a plurality of divided cores having a shape obtained by dividing an annular core in a circumferential direction, the divided cores being made of a soft magnetic material; a core gap part disposed between the divided cores in the annular core formed by combining the plurality of divided cores, the core gap part being made of a non-magnetic material; annular heat-dissipating cases that house the divided cores and the core gap part; and a coil wound around the heat-dissipating cases, wherein the heat-dissipating cases are made of a material whose thermal conductivity is as high as 100 W/(m·K) or more.
