PROBLEM TO BE SOLVED: To provide a biological information analysis method and a biological information analysis device which are useful to lifestyle guidance of a user by efficiently analyzing the correlation among two or more types of biological information.SOLUTION: One feature point is specified by comparing first biological information with a prescribed threshold about a plurality of pieces of biological information accompanied with measuring date information. Then, the value of second biological information existing on the same time axis as the feature point is determined as a correlation point. Next, a change in the amount of fluctuation of the second biological information centering on the correlation point, that is, an inclining degree of a graph of the second biological information is calculated. Then, a point on another time axis approximate to the change in the amount of fluctuation of the second biological information is searched, and the point is determined to be an approximate point. Further, a measurement value of the first biological information on a measuring date of the approximate date is specified as a feature point candidate, and the feature point candidate is displayed in a display part.
