Provided is a pulse wave measuring device capable of expanding a pulse wave detection range with a simple configuration and measuring an accurate pulse wave. The pulse wave measuring apparatus includes an acceleration sensor that detects vibration and a vibration transmission unit that transmits vibration due to pulsation at a measurement site, and the length of the vibration transmission unit in a specific direction is the length of the acceleration sensor. Longer than the direction length.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。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。
