The invention relates to a TLCP (Thermotropic Liquid Crystal Polyester)-reinforced conductive TiO2/PA composite material. The composite material comprises the following components by weight percent: 30% to 80% of polyamide, 1% to 30% of conductive TiO2, 5% to 40% of TLCP and 0.01% to 10% of aiding agent. The TLCP is successfully applied to the conductive TiO2/PA composite material, so that the high machining fluidity of the conductive TiO2/PA composite material is achieved. Thus, the conductive TiO2/PA composite material is suitable for machining of thin-walled parts, and has the good mechanical property. Meanwhile, the characteristics of other conductive polyamide materials (such as carbon black or materials in which carbon fibers are added) which are less prone to color blending and poor in temperature endurance and selectivity (functions cannot be exerted well unless the good compatibility exists between macromolecular materials and a basal body) are successfully overcome due to the application of the cond
