The present disclosure relates to a tire cord fabric, a method of manufacturing the same, a sheet including the same, and a tire including the sheet, and the tire cord fabric includes a plurality of tire cords which are arranged in parallel to each other, a weft yarn which weaves the tire cords to conduct a weaving operation, and a conductive fiber which comes into contact with the surface of the tire cord and is extended in a longitudinal direction of the tire cord. The tire cord fabric can effectively discharge static electricity aggregated in a tire by mixing a tire cord with a conductive fiber, thereby weaving a mixture of the tire cord and the conductive fiber. Particularly, the tire cord fabric can secure an effective conductive passage since the conductive fiber is extended in a radial direction from bead parts to a tread part as in a carcass cord. Therefore, the tire cord fabric can simultaneously accomplish solving of a static electricity problem and obtaining of a fuel efficiency improving effect through low rolling resistance as a result by decreasing a demand associated with electrical conductivity of a rubber composition for sidewall and a rubber composition for topping, thereby enabling a rubber composition having a low loss modulus (E″) for improving rolling resistance to be applied.
