    摘要： Provided are a bipolar plate that can decrease the internal resistance of a flow battery, a redox flow battery, and a method for producing a bipolar plate. A bipolar plate sandwiched between a positive electrode in which a positive electrode electrolyte flows and a negative electrode in which a negative electrode electrolyte flows includes a positive-electrode-side surface in which a flow channel having a plurality of grooves through which the positive electrode electrolyte flows is provided and a negative-electrode-side surface in which a flow channel having a plurality of grooves through which the negative electrode electrolyte flows is provided. Each of the flow channels includes an inflow channel through which the electrolyte flows into the electrode and an outflow channel through which the electrolyte flows out of the electrode, the inflow channel and the outflow channel are not in communication with each other and are independent from each other, and the grooves each have a wide portion inside the groove, the wide portion having a width larger than a width of an opening of the groove.
