Abstract
A method of manufacturing a molded coil for use in an electric apparatus such as a molded transformer or a reactor. The method includes the steps of covering a winding with an insulating prepreg, curing the prepreg under heat, and casting a synthetic resin around the prepreg. The method makes it possible to minimize any thermal stress that may develop in the molded resin layer.
