An apparatus for evaluating a vascular endothelial function includes a first cuff wrapped around one of right and left upper or lower limbs of a subject, a second cuff wrapped around the one of the right and left upper or lower limbs, a third cuff which is to be wrapped around another one of the right and left upper or lower limbs, a cuff pressure controller which controls pressures that are applied to the first cuff, the second cuff and the third cuff, respectively, a cuff pressure detector which detects cuff pressures in the second cuff and the third cuff, a pulse wave detector which detects respective pulse waves at the second cuff and the third cuff from outputs of the pressure sensors.
