The present invention is a blood pressure measurement system (1000) for measuring a blood pressure at a predetermined measurement site of a subject, comprising: a blood pressure measurement system (1000) for measuring a blood pressure of a subject to be measured by a finger of a measurer so that the measurement site is recessed A device (25), and a blood pressure measuring device (26) for measuring blood pressure based on information from the measuring device (25). The measurement device (25) includes an average blood pressure detection unit (5) for detecting information on the pressure of the measurement device (25) applied to the measurement site by the force of the finger of the measurer, and a measurement unit And a blood pressure change amount detection unit (4) that contacts the site and detects minute changes due to the pulse of the measurement site. The processing unit (28) of the blood pressure measuring device (26) calculates the mean blood pressure (BP) based on the information of each pressure acquired from the blood pressure change amount detection unit (4) and the mean blood pressure detection unit (5) of the measurement device (25) , Systolic blood pressure, diastolic pressure.本発明は、被検者の所定の計測部位の血圧を計測する血圧計測システム(1000)であって、血圧の計測時に、計測部位が凹むように、測定者の指によって計測部位に押し付けられる測定装置(25)と、測定装置(25)からの情報に基づいて血圧を計測する血圧計測装置(26)と、を備える。測定装置(25)は、測定者の指の力によって計測部位に加えられた測定装置(25)の圧力の情報を検知する平均血圧検知部(5)と、平均血圧検知部(5)とともに計測部位に接触し計測部位の脈による微小な変化を検知する血圧変化量検知部(4)と、を備える。血圧計測装置(26)の処理部(28)は、測定装置(25)の血圧変化量検知部(4)と平均血圧検知部(5)から取得したそれぞれの圧力の情報に基づいて、平均血圧、最高血圧、最低血圧を計算する。
