A carotid pulse measurement device provided for measuring carotid pulse of a user's neck includes a band, an artery-pressing air cell, an inflating/deflating device, and a pressure detection unit. The band functions to surround the user's neck. The air cell is arranged in the band and is fluidly connected to the inflating/deflating device for selectively inflating/deflating the air cell. The pressure detection unit detects variation of pressure inside the air cell. To use the measurement device, the band is put around the user's neck with the air cell positioned exactly corresponding to the carotid artery of the neck so that the pressure detection device detects the pressure variation and generates a digital pulse signal, which is employed to calculate arteriosclerosis index of the user for evaluation the degree of arteriosclerosis of the user.
