PROBLEM TO BE SOLVED: To accurately and easily calculate living body information by forming plural passages up to light receiving parts from light emitting parts, and calculating the living body information on the basis of a received light signal from the passage higher in accuracy among plural received light signals obtained from the respective passages. SOLUTION: Plural light emitting parts 4Aa to 4Ac and light receiving parts 5Aa to 5Ac are alternately arranged in close contact on a tip surface of a sensor 1A for measuring living body information such as a subcutaneous fat thickness, a body fat rate and a blood sugar value of a subject, the output signal of the sensor 1A is inputted to a signal processing part 6A to calculate the living body information, and the calculation result is displayed on a display part 7A. At this time, when measuring the body fat rate, the light is projected toward the subject from the other light emitting parts 4Aa, 4Ac by excluding a signal on the basis of the light passing through a blood vessel of the subject, for example, like the light projected from the light emitting part 4Aa and incident on the light receiving part 5Aa, and the living body information is calculated by using only a signal on the basis of the light incident on the light receiving parts 5Aa, 5Ac.
