Semiconductor device

The present invention provides a molding precursor for a fiber-reinforced polyimide resin molded article, which is formed by impregnating a functional fiber with an addition-reaction type polyimide resin. The molding precursor has a melt viscosity in the range of 300 to 3200 kPa·s under conditions of keeping for 1 to 10 minutes at a temperature 5 to 20° C. lower than the thickening-start temperature so as to effectively prevent a fiber-reinforced polyimide resin molded article from warping. The present invention provides also a method for producing the molding precursor.
