PROBLEM TO BE SOLVED: To manufacture a titanium thin sheet having a thickness of 500 μm or less, for instance, with an energetically efficient process, specifically, a process having a small number of steps. SOLUTION: This manufacturing method includes: a step of molding a viscous composition containing a metal powder, a binder, a plasticizer and a solvent into a thin sheet shape, and drying the composition to produce a mold to be sintered; a sintering step of sintering the mold to be sintered to produce a sintered thin sheet; a consolidating step of consolidating the sintered thin sheet to produce a sintered and consolidated thin sheet; and a resintering step of resintering the sintered and consolidated thin sheet. The metal powder is a titanium powder, a titanium hydride powder and/or a titanium alloy powder. The density ratio of the sintered and consolidated sheet is 70% or more. When the sintering temperature for the mold to be sintered is represented by T<SB>1</SB>°C, and the resintering temperature for the sintered and consolidated thin sheet is represented by T<SB>2</SB>°C, the temperatures satisfy the expressions of 900<T<SB>1</SB>≤1,300, 1,000<T<SB>2</SB>≤1,400, and T<SB>1</SB>+50<T<SB>2</SB>.
