PROBLEM TO BE SOLVED: To provide a more inexpensive device for acquiring information of blood which can obtain results with excellent reproducibility of measurement. SOLUTION: The device includes a portable cylindrical part one end of which is an opening end to which a finger is inserted and the other end a contacting end, and a semiconductor element which emits light with an absorption wavelength for hemoglobin, and has a light source housed in the portable cylindrical part. Also, the device is equipped with a light-receiving part which is housed in the portable cylindrical part in a state where the light-receiving surface is directed to the light source, and a light-blocking part which is mounted on the end of the opening in the portable cylindrical part. In the light-receiving part, to calculate a comparison value with data of a transmitted light intensity of a subject's finger which was previously acquired, data of a transmitted light intensity of the finger is acquired.
