  "textContent": "An electrolytic copper foil having higher electrical conductivity, and a method for producing the same are provided. The electrolytic copper foil according the present invention has a carbon content of 5 ppm or less, a sulfur content of 3 ppm or less, an oxygen content of 5 ppm or less, and a nitrogen content of 0.5 ppm or less; has a total content of carbon, sulfur, oxygen, nitrogen, and hydrogen of 15 ppm or less; and has a number of grains of 8.0 to 12.0/μm, the number of grains changing to 0.6 to 1.0/μmby heating the electrolytic copper foil at 150° C. for 1 hour. A method for producing this electrolytic copper foil includes cleaning a copper raw material; dissolving the copper raw material after the cleaning to obtain an electrolytic solution having a total organic carbon (TOC) of 10 ppm or less; and electrolyzing the electrolytic solution to obtain the electrolytic copper foil.",
