To provide a pyridobisimidazole textile fabric which can be used also for application requiring uniformity of woven fabric, such as a screen gauze for precision printing and a filter for filtration, and can be developed to various application, using characteristics such as high strength, heat resistance, and flame retardance of pyridobisimidazole fiber.

The pyridobisimidazole textile fabric has warp and/or weft using a pyridobisimidazole fiber in the presence of pyridobisimidazole crystals in which S2/S1 satisfies 0.1-1.5, when diffraction peak area derived from crystal (200) face in equatorial profile is defined as S1 and diffraction peak area derived from crystal (110) face, (210), face and (400) is defined as S2 in an electric diffraction diagram obtained from the surface part (1 m from the surface) of the pyridobisimidazole fiber.
