The electrical insulating whisker is blended in the thermosetting resin. After uniformly dispersing the whisker in the thermosetting resin by stirring, it is applied onto a roughened surface of the copper foil wherein at least one side is roughened, and a copper- clad laminate is manufactured by using a prepreg with the copper foil manufacture by removing a solvent by heating and drying. |
