Abstract
The present invention is directed to a prepreg comprising a fiber base material impregnated with a resin composition which comprises a polyamide-imide resin and a thermosetting resin as essential components, and a metal-clad laminated sheet obtained by pressing the prepreg and a metal foil having a surface roughness: Rz≦3.0 together while heating. In addition, the present invention provides a heat-resistant laminated sheet which is excellent in micro-wiring formation properties, thermal shock resistance, reflow resistance, and crack resistance.
