PURPOSE: To provide a copper-clad laminated plate made of, as a base material, an aramid fiber unwoven fabric having a small coefficient of thermal expansion and a high heat resistance at the time of moisture absorption. CONSTITUTION: An aramid fiber unwoven fabric is impregnated with a resin and dried so as to obtain a prepreg. A copper foil is superposed on the prepreg so as to form a body to be pressed. The body to be pressed is heated and pressed until a cured plate thickness of the prepreg becomes 60-80% of the thickness of the prepreg. |
