A method of producing a continuously cast metal rod capable of producing a high-quality continuously cast material is provided. In the method of producing a continuously cast metal rod, a cooling liquid is supplied to each of outer peripheral surfaces of a plurality of ingots extracted from a plurality of molds in parallel to cool each of the plurality of ingots. In a predetermined ingot, the number of adjacent ingots is the number of other ingots arranged around the predetermined so as to face the predetermined ingot, and an ingot small in the number of adjacent ingots is cooled with weak cooling in which the degree of cooling by the cooling liquid is reduced with respect to an ingot large in the number of adjacent ingots.
