摘要: A biological information analyzing device includes: an indicator extraction unit that extracts, from blood pressure waveform data measured continuously by a sensor that is worn on a user's body and can non-invasively measure a blood pressure waveform for each of heartbeats, an indicator expressing a load placed on the user's heart by an activity, and a processing unit that outputs the indicator extracted by the indicator extraction unit. The indicator extraction unit finds the indicator on the basis of a difference between a blood pressure waveform in a resting section corresponding to when the user is in a resting state and a blood pressure waveform in an active section corresponding to when the user is engaged in the activity.
