PROBLEM TO BE SOLVED: To provide a blood pressure measuring system that can be occasionally or continuously measurable considering correcting a tension generated when mounting for achieving accurate blood pressure measurement.SOLUTION: The blood pressure measuring system using three axial force measurement sensor 4 for detecting force acting on three axial directions includes: a sensor part 2 for pressurizing against a vascular wall and mounting； a brain wave transmission member for transmitting a pulse wave generated by the vascular wall； and a control part 5 for detecting pressures of the pressure direction component and the shearing direction component and calculating a blood pressure value by the pressures.
