PROBLEM TO BE SOLVED: To provide a coil-sealing resin-forming reactor in which peeling between a packaging case and a soft magnetic resin forming core, and damages to the packaging case can fully be prevented and vibrations to the outer part and noise radiation can be reduced. SOLUTION: A thermal expansion difference absorbing layer 7, superior in elastic deformation, is interposed between the soft magnetic resin forming core 5 where a coil 1 is embedded and a case 4 surrounding the core 5. Thus, peeling of the case 4 and the soft magnetic resin forming core 5 due to the difference between them, and a crack of the case 4 due to magnetic vibration of the soft magnetic resin forming core 5 can be prevented.
