A measurement device (1) performs filtering processing via an analog filter (403) with a predetermined transfer function on a first signal indicating a pulse wave of a subject and a second signal indicating a pulse wave or an electrocardiogram of the subject； performs filtering processing via a digital filter with the predetermined transfer function on third time series data, which is first time series data of the first signal arranged in reverse chronological order, and fourth time series data, which is second time series data of the second signal arranged in reverse chronological order； and calculates a pulse transit time on the basis of a signal indicated by fifth time series data, which is the third time series data post filtering processing arranged in chronological order, and a signal indicated by sixth time series data, which is the fourth time series data post filtering processing arranged in chronological order.
