    Abstract: A measurement device includes a pulse wave signal acquisition unit, a pulse wave velocity calculator, a transfer function calculator, a phase diagram classifier, and an aneurysm determinator. The pulse wave signal acquisition unit acquires time-series pulse wave signals of each of an upper arm and an ankle of the subject. The pulse wave velocity calculator obtains a brachial-ankle pulse wave velocity based on the pulse wave signal of the upper arm and the pulse wave signal of the ankle. The transfer function calculator calculates a transfer function from the pulse wave signal of the upper arm and the pulse wave signal of the ankle. The phase diagram classifier classifies the phase diagram of each subject into any one of four groups. The aneurysm determinator determines presence or absence of the abdominal aortic aneurysm by a criterion set according to each group.
