This biological information analysis device is provided with: an index extracting unit which is attached to the body of a user, and which, on the basis of time series data of blood pressure waveforms, in which the blood pressure waveform of each heartbeat is continuously measured by a sensor capable of non-invasive measurement, forms a multidimensional drawing by plotting, in a multidimensional space formed by a plurality of axes at least including two axes corresponding to two types of feature values extracted from the blood pressure waveforms, a plurality of data points constituting one or a plurality of blood pressure waveforms selected from the time series data of blood pressure waveforms, and extracts an index relating to a form-related feature of the multidimensional drawing; and a processing unit which performs processing based on the extracted index. |
