Abstract
A small reactor with high heat-release performance is provided. A reactorincludes an assembly () and a case (), the assembly () having a coil () and a magnetic core () at which the coil () is arranged, the case () housing the assembly (). The case () includes a bottom plate () that contacts a fixing object when the reactor () is installed on the fixing object, a side wall () that is mounted on the bottom plate () with an adhesive and surrounds the assembly (), and a junction layer () that fixes the coil () to an inner surface of the bottom plate (). The bottom plate () is formed of a material with higher thermal conductivity than that of the side wall (). The reactor () easily transfers heat of the coil () to the bottom plate () and hence has high heat-release performance because the reactor () includes the bottom plate () with the high thermal conductivity and the coil () is joined to the bottom plate () through the junction layer (). Since the bottom plate () and the side wall () are integrated using the adhesive, the thicknesses of both the members () can be decreased. Accordingly, the reactor () is small.
