Zusammenfassung:PROBLEM TO BE SOLVED: To provide an organic polymer fiber having high electrical insulating properties while having high heat conductivity and suitable for heat-conductive members having heat conductivity only in a specific direction. SOLUTION: In the heat-resistant organic fiber having high heat conductivity, heat conductivity in the fiber axis direction at 200K is at least ≥0.5 W/cm and is at least ≥20 times higher, compared with heat conductivity in a direction which is vertical to fiber axis and thermal diffusivity coefficient in fiber axis direction at 200K is at least 10 mm2and is at least ≥20 times higher, compared with thermal diffusivity coefficient in a direction which is vertical to the fiber axis and the thermal decomposition temperature or the melting point is ≥250°C.
