Zusammenfassung:	A galvanized steel sheet for hot forming, the galvanized steel sheet including a galvanized film provided on a surface of a steel sheet, wherein the steel sheet has a chemical composition consisting of, in mass%, C: 0.02% to 0.58%, Mn: 0.5% to 3.0%, sol. Al: 0.005% to 1.0%, a predetermined element(s) as necessary; Si: less than or equal to 2.0%, P: less than or equal to 0.03%, S: less than or equal to 0.004%, N: less than or equal to 0.01%, and the balance: Fe and impurities, wherein a content of Mn in a portion from an interface of the steel sheet and the galvanized film to a depth of 5 µm is more than or equal to 0.3 mass %, wherein the galvanized film has a plating coverage of 40 g/m 2 to 110g/m 2 , an Al content of more than or equal to 150 mg/m 2 within the galvanized film, and an Al concentration of less than or equal to 0.5 mass %, and wherein the galvanized steel sheet is used for an application in which the galvanized steel sheet is heated to 700°C or above and is then subjected to hot forming.
