A vascular-endothelial-cell-function evaluating apparatus (10) comprising a pressing device (12, 16, 18, 24, 26, 50; 66) including a cuff (12) that is adapted to be worn on a first portion (14) of a living subject, and a cuff-pressure changing device (16, 18, 24, 26, 50) that changes a pressure in the cuff so as to press the first portion of the subject in a pressing period; a pulse-wave detecting device (16, 28) that detects a pulse wave including a plurality of heartbeat-synchronous pulses, from the first portion of the subject, or a second portion of the subject located on a distal side of the first portion; and a pulse-wave-second-half-information obtaining device (42, 52; 70) that obtains a plurality of sets of pulse-wave-second-half information that represent respective characteristics of respective second-half portions of respective heartbeat-synchronous pulses of the pulse wave that are detected by the pulse-wave detecting device at respective different times, the respective second-half portions of the respective heartbeat-synchronous pulses being respective portions of the respective pulses that are subsequent to respective peak points of the respective pulses, the pulse-wave-second-half-information obtaining device providing a time-wise change of the sets of pulse-wave-second-half information that is caused by the pressing of the pressing device. <IMAGE>
