PROBLEM TO BE SOLVED: To provide a hemoglobin quantification device and the like capable of clearly outputting the metabolic state of a bio-element by non-contact and non-invasively calculating and quantifying the total hemoglobin amount of a living tissue. SOLUTION: A light receiving section 2 which receives reflected light from a biological tissue a and which receives arbitrary two narrow wavelength band components and white components having different reflection characteristics depending on the oxygen saturation of hemoglobin； A hemoglobin amount calculation unit 8 that calculates the amount of hemoglobin of the hemoglobin based on the light components in the two narrow wavelength bands acquired from the light components that are obtained, and the hemoglobin amount calculation unit 8 includes the two narrow wavelength bands. The light component in is corrected based on the blue component and the green component to calculate the hemoglobin amount.
