    摘要： Provided is a fiber fabric excellent in high mechanical strength and shapability. The fiber fabric comprising warps and wefts: wherein either one of the warps and the wefts is configured by a polyamide resin fiber composed of a polyamide resin composition, and the other is configured by a continuous carbon fiber; in an arbitrary square area of the fiber fabric, one side of the arbitrary square area is aligned in parallel to the warps, and other one side of the arbitrary square area is aligned in parallel to the wefts, the continuous carbon fiber has an average length 1.1 to 1.6 times longer than the length of a side of the square; the polyamide resin composition contains a polyamide resin in which 50% by mole or more of diamine structural units thereof is derived from xylylenediamine; and wherein the polyamide resin has a number-average molecular weight (Mn) of 6,000 to 30,000, and 0.5 to 5% by mass of the polyamide resin has a molecular weight of 1,000 or smaller.
