The present invention relates to a reduction electrode for electrolysis and a manufacturing method thereof, the reduction electrode including a metal substrate and an active layer positioned on at least one surface of the metal substrate, wherein the active layer includes a ruthenium oxide, a platinum oxide, and a cerium oxide, and when the active layer is uniformly divided into a plurality of pixels, the standard deviation of the composition of ruthenium between the plurality of pixels formed by uniformly dividing the active layer is 0.4 or less, and N atoms in the active layer are present in an amount of 20-60 mol% based on ruthenium. According to the present invention, the overvoltage of a reduction electrode for electrolysis may be reduced and the durability thereof may be increased.
