PROBLEM TO BE SOLVED: To provide a biological information measurement device capable of measuring biological information such as pulse wave velocity with a high degree of precision with little labor for mounting a measuring tool, and with a simple configuration.SOLUTION: An electrode 111 and an electrode 112 are provided to a first cuff 110 and a second cuff 120 respectively, and, using the electrodes 111 and 112, an impedance pulse wave is measured. Thereby, simply by mounting the first cuff 110 and the second cuff 120 on a predetermined region of a subject, the impedance pulse wave and a pressure pulse wave can be measured, and based on them, a pulse wave velocity of a high degree of precision can be calculated. Consequently, with little labor for mounting a measuring tool, and with a simple configuration, the pulse wave velocity can be measured with a high degree of precision. Furthermore, using the first cuff 110 and the second cuff 120, electrocardiogram and blood pressure can also be measured.
