1. A central blood pressure waveform estimation device comprising:

  • a pulse wave detection section which non-invasively detects a peripheral pulse wave;

    a transfer function storage section which stores a transfer function calculated in advance based on a waveform of the peripheral pulse wave detected by the pulse wave detection section and a measured central blood pressure waveform corresponding to the peripheral pulse waveform; and

    a central blood pressure waveform calculation section which calculates a central blood pressure waveform corresponding to a waveform of a peripheral pulse wave newly detected by the pulse wave detection section, based on the newly-detected peripheral pulse waveform and the transfer function; and

    a central blood pressure waveform index derivation section which derives an index from a central blood pressure waveform calculated by the central blood pressure waveform calculation section.
