PROBLEM TO BE SOLVED: To provide a biological light measuring device capable of accurately measuring the position of a measuring part in a subject. SOLUTION: A control part measures a distance between a first point and a feature point from the change of a detected light quantity when irradiating the subject with light and detecting it between first and second points at a known interval on a mounting part and a detected light quantity when irradiating the subject with light and detecting it between the feature point P1 on the subject and the first point, and displays the position of the measuring part for the feature point at a display part.
