An electrolytic copper solution for producing an electrolytic copper foil is provided which can improve elongation properties while reducing the profile of the rough surface. The electrolytic solution for electrolytic-copper foil production is a sulfuric-acid-acidified aqueous copper sulfate solution containing: bromide ions derived from bromine, an inorganic acid thereof, an inorganic salt thereof, or a mixture of these; a glue; and chloride ions. |
