PROBLEM TO BE SOLVED: To provide a titanium plate for a drum for manufacturing electrolytic Cu foil and a manufacturing method therefor, which can manufacture the electrolytic Cu foil of high quality having few macro-patterns on the surface of the plate. SOLUTION: This titanium plate comprises, by mass%, 0.5-2.1% Cu, 0.04% or less Fe, 0.1% or less oxygen, and the balance titanium with unavoidable impurities, and has a homogeneous fine recrystallization structure. The manufacturing method comprises steps for heating a slab composed of the content to the temperature range of the two phases ofα+β, hot-rolling it, and annealing it in the temperature range of theβtransformation point or lower. The manufacturing method further comprises steps for cold-rolling the plate, and annealing it in the temperature range of theβtransformation point or lower. Annealing in the temperature range of anαsingle-phase particularly gives it higher quality. COPYRIGHT: (C)2004,JPO
