PROBLEM TO BE SOLVED: To provide a lead feed pipe adapted to drastically reduce the deposits to be deposited within the lead feed pipe even in conveying a molten lead alloy in which aluminum (Al) or arsenic (As) is contained and to thereby drastically reduce a maintenance cost. SOLUTION: The lead feed pipe performs conveyance of a molten lead alloy containing the aluminum or the arsenic and is used in a heat retaining state of 450 to 640°C. The lead feed pipe of an iron alloy system contains 24 mass% or more, in total, elements of at least two or more kinds selected from the group consisting of nickel, molybdenum, niobium, chromium, vanadium, and zirconium.
