1. A blood pressure information measurement device for calculating an index of a degree of arteriosclerosis of a measurement subject as blood pressure information, comprising:

  • a detection member comprising a plurality of pressure sensors; and

    a central processing unit that detects a pulse waveform by bringing the detection member into contact with an exterior of a measurement site of the measurement subject,wherein the central processing unit;

    acquires factor information for the degree of arteriosclerosis;

    stores a plurality of pseudo blood flow waveforms;

    generates a waveform estimated as a blood flow waveform by compositing the plurality of pseudo blood flow waveforms based on the factor information;

    decomposes the pulse waveform into waveforms of an ejected wave and a reflected wave using the pulse waveform and the waveform estimated as the blood flow waveform; and

    calculates the index of the degree of arteriosclerosis from a relationship between the ejected wave and the reflected wave obtained by decomposing the pulse waveform.
