The present invention relates to a bipolar plate with fibrous conductive materials inserted into the flow path and a redox flow battery including the bipolar plate.It is possible to realize the redox flow battery having an excellent energy efficiency while improving the charging/discharging capacity and efficiency regardless of the flow rate of the electrolyte solution, by increasing the retention time of the electrolyte solution in the flow path by the fibrous conductive materials to increase the chance of reaction with the electrode layer.
