Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a nonwoven fabric for a body warmer excellent in dimensional stability, flexibility, texture, etc., and to provide a disposable body warmer. SOLUTION: On at least one surface of a long-fiber nonwoven fabric layer (A) having basis weight of 10 to 50 g/m2and an average fiber diameter of 7 to 30μm, a short-fiber web layer having an average fiber diameter of 7 to 30μm is laminated and it is integrated by fluid entanglement to obtain a composite nonwoven fabric. The basis weight of the nonwoven fabric is 30 to 120g/m2, a basis weight conversion value of 5% intermediate stress is ≥0.5N/5cm vertically and ≥0.05N/5cm horizontally, width reduction in the case of 5N/5cm loading is ≤10%, and a cross section fiber constitution of the nonwoven fabric is rough and fine in the nonwoven fabric for the body warmer.
