Abstract:
1. A reactor comprising an assembly that has a coil and a magnetic core on which the coil is disposed, and a case that houses the assembly, the case comprising: an installation face portion that can be fixed to a fixing target when the reactor is installed on the fixing target; a side wall portion that is formed separately from the installation face portion, attached to the installation face portion, and surrounds the periphery of the assembly; and a heat dissipation layer that is formed on an inner face of the installation face portion and is interposed between the installation face portion and the coil, wherein the thermal conductivity of the installation face portion is greater than or equal to the thermal conductivity of the side wall portion, and the heat dissipation layer is constituted by an insulating material whose thermal conductivity exceeds 2 W/m·K.
