A cable bead (10) includes: a core (1) composed of an annularly formed steel; and a sheath (3) composed of at least one sheath layer, which is formed by spirally winding a sheath filament (2) composed of a steel around the core (1). The sheath filament (2) has a carbon content of higher than 0.90% by mass but 0.95% by mass or less, and a chromium content of 0.15 to 0.30% by mass.
