A light-transparent fabric, as may be affixed to an artificial leather or incorporated in an automotive interior, consists of two fabric layers which are parallel to each other and spaced apart and a support layer which connects the two fabric layers together. The support layer is formed of connecting yarns, and the fabric layers are woven from fabric yarns. The meshes formed in the first fabric layer are the first meshes while the meshes formed in the second fabric layer are the second meshes, and 80%-100% of the first meshes align with the second meshes one by one. At least 80% of the support threads in the connecting yarns are arranged in the shape of an I. The ratio of the diameter of the connecting yarns to the diameter of the fabric yarns is 1.1:1.5. The light-transparent fabric has both high transmittance and high mechanical performance.
