An apparatus for evaluating a vascular endothelial function includes: a cuff (11), to be wound around a part of a body of a subject a cuff pressure controller (20), configured to control a pressure of the cuff, and configured to apply continuous pressure stimulation a cuff pressure detector (31), configured to detect the pressure of the cuff from output of a pressure sensor (14) connected to the cuff a pulse wave detector (32), configured to detect, from the output of the pressure sensor, pulse waves before and after the continuous pressure stimulation is applied and an analyzer (33), configured to evaluate the vascular endothelial function by comparing the pulse waves detected before and after the continuous pressure stimulation is applied.
