To provide a pulse wave measurement device that is capable of extending the range of pulse wave detection with a simple configuration and achieving accurate pulse wave measurement.SOLUTION: The pulse wave measurement device includes: an acceleration sensor that detects a vibration and a vibration transmission unit that transmits a vibration caused by pulsation in a measured site. The length of the vibration transmission unit in a specific direction is longer than the length of the acceleration sensor in a longitudinal direction.SELECTED DRAWING: Figure 1【課題】 簡易な構成で脈波の検知範囲を広げられ、正確な脈波が測定可能な脈波測定装置を提供する。【解決手段】 脈波測定装置は、振動を検知する加速度センサと、被測定部位における脈動による振動を伝達する振動伝達部と、を有し、前記振動伝達部の特定方向の長さが、前記加速度センサの長手方向の長さよりも長い。【選択図】 図１
