[Problem] To provide a blood pressure meter which simplifies the structure of the cuff and makes it possible to easily and definitively wrap the cuff tightly around the upper arm of a patient. [Solution] The cuff (3) of a blood pressure meter (1) is equipped with: a body member (80) having a blood-restricting airbag (20) for restricting the flow of blood in the upper arm (T) by supplying air, and formed by folding a sheet-shaped member (50) and sealing the same so as to be airtight an arterial-pulse-detection airbag (40) for detecting the pulse of an artery in the upper arm (T) by supplying air, and positioned in the blood-restricting airbag (20) of the body member (80) and a surface fastener (60) provided on the body member (80) and having one member (61) and another member (62) which is attachable to and detachable from the one member (61). Therein, the one member (61) of the surface fastener (60) is positioned on the blood-restricting airbag (20) of the body member (80), while the other member (62) of the surface fastener (60) is attached to the arm-winding section (96) of the body member (80) instead of to the blood-restricting airbag (20) thereof, by stitching formed by opening a through-hole in the arm-winding section (96) by passing a thread therethrough.[Problème] Fournir un tensiomètre qui simplifie la structure du brassard et rend possible lenroulement facile et définitif du brassard fermement autour de larrière-bras dun patient.
