Abstract
A biological analysis device includes: a pulse pressure calculation unit that calculates a pulse pressure index related to a pulse pressure of a biological body; an average blood pressure calculation unit that calculates an average blood pressure index related to an average blood pressure of the biological body; and a blood pressure calculation unit that calculates a systolic blood pressure and a diastolic blood pressure in accordance with the pulse pressure index and the average blood pressure index. At least one of the pulse pressure index and the average blood pressure index is calculated in accordance with a blood flow index which is calculated from an intensity spectrum related to a frequency of light reflected and received from an inside of the biological body through radiation of a laser beam and is related to a blood flow of the biological body.
