Provided is a radial arterial pulse sensing apparatus for noninvasive and continuous measurement of blood pressure and arterial elasticity. The apparatus includes two pressure sensor for detecting radial arterial pulses, two cuffs that are disposed under the respective pressure sensors and expandable by application of external pressure, a motor unit for providing proper pressure to expandable pouches under the respective pressure sensors in a state where a wrist band having the pressure sensors is put on a wrist, a pulse wave velocity calculating unit that calculates a pulse wave transfer velocity to attain a blood pressure value using an output from the pressure sensors, and an augmentation index calculating unit that estimates the blood pressure value by finding a time point of a reflective wave of the pulses using the outputs from the pressure sensors.
