System for measuring biological information, method for measuring biological information, blood sugar meter, body composition meter and sphygmomanometer

Provided is a system for measuring biological information whereby an attribute of biological information that is determined on the basis of the situation in which the biological information is measured can be automatically determined. Thus, the user's convenience can be improved. An apparatus for obtaining biological information characterized by comprising: a communication section (155) for obtaining body movement detection unit data (D1) relating to movements of a body; a communication section (155) for obtaining blood sugar meter data (D2), body composition meter data (D3), or sphygmomanometer data (D4) of said body; and a means for determining the attributes of the blood sugar meter data (D2), body composition meter data (D3) and sphygmomanometer data (D4) of said body on the basis of the body movement detection unit data (D1).
