A vascular endothelial function inspection apparatus includes a first cuff that is mounted to a first part of a subject, a cuff pressure control unit that controls a pressure applied to the first cuff, a pressure sensor that is connected to the first cuff, a cuff pressure detection unit that detects a cuff pressure from an output of the pressure sensor, a pulse wave detection unit that detects pulse waves from the output of the pressure sensor, a blood pressure measuring unit that measures a blood pressure value based on the cuff pressure and the pulse waves, a storage unit that stores therein an elasticity index value indicating an elasticity of a blood vessel of the subject, and an analysis unit that performs data processing for evaluating an endothelial function of the blood vessel.
