Abstract:
A reactor that comprises: an assembly of a coil and a magnetic core; a case that houses the assembly thereinside; a sealing resin part that packs the inside of the case and seals at least a portion of the assembly; and a heat dissipation member that is interposed between the coil and the case. The case has: an inside bottom surface on which the assembly is mounted; and a pair of coil-facing surfaces that face side surfaces of the coil. The pair of coil-facing surfaces have inclined surfaces that are inclined so as to separate from each other from the inside bottom surface side toward the side opposite the inside bottom surface. The coil comprises: a first wound part that is arranged on the inside bottom surface side; and a second wound part that is arranged on the opposite side of the first wound part from the inside bottom surface side. The first wound part and the second wound part are vertically stacked such that the axes thereof are parallel. The first wound part and the second wound part have the same width. The heat dissipation member has a first heat dissipation part that is interposed between at least one of the inclined surfaces and the second wound part.
