Beschreibung
Zusammenfassung:	An object is to provide an output-noise reduction device in which a component encapsulated through insert molding can be appropriately protected. In a noise filter module (output-noise reduction device), a conducting bar and a magnetic body core are protected with a molded member formed through insert molding. The molded member is formed of a resin material with a molding shrinkage rate of 0.5% or less. Thus, the amount of shrinkage after the molded member is molded and stress as a result of the shrinkage can be made small, whereby damage on the magnetic body core, deformation of a lead frame, and the like can be prevented from occurring.
