PROBLEM TO BE SOLVED: To provide a binding braid for a motor of an electric car, scarcely causing damage to bound components of the motor, having high performance in binding operation, and having an excellent high-temperature oil-resisting performance. SOLUTION: This binding braid for the motor of the electric car is formed by using synthetic fiber multi-filament yarn having a melting point or decomposition temperature of≥280°C and so structured that 8 or more strands of the yarn are together twined to form a round structure, and has the high-temperature oil-resisting performance [expressed by (T'/T)×100 in %; T is a tensile strength of the binding braid before treatment; and T' is a tensile strength of the binding braid after treatment] of≥50%, wherein the tensile strength is measured by a method specified in 8.5.1 of JIS L1013, and the treatment means such treatment that the binding braid is wholly put into a mixture of 5wt.% of water and 95% of an automatic transmission fluid contained in a closed container and the container is heated in such a manner that a temperature of the mixture in the container is kept at 150°C for 1,000hr.
