A boot-band that (a) does not excessively clamp a boot, (b) can prevent leakage of grease from the boot and the boot-band, and (c) uniformly produces a tight contact force on the boot without deteriorating the contact force on the boot. This boot-band includes a metallic belt-shaped member (2), and its clamping force, which is generated in the direction that shortens the circumference of the metallic belt-shaped member (2), is exercised under a ring-shaped condition in such a way that one end of the metallic belt-shaped member overlaps the other end thereof, and in such a way that both ends are wound around the outer periphery of the boot. A smaller-cross-sectional area (5a) is formed in a part of the belt-shaped member (2); the smaller-cross-sectional area (5a) and the general part (8), whose cross-sectional area is not reduced, are elongated due to plastic deformation caused by the clamping force.
