Body fat measurement device

A body fat measurement device comprising:

• a plurality of electrodes comprising back area electrodes for making contact with a surface of a back area that is an area on a back side of a trunk area of a measurement subject, and upper limb electrodes for making contact with a surface of upper limbs of the measurement subject;
• a body impedance measurement unit for measuring a body impedance of the measurement subject's body using said plurality of electrodes;
• a body composition information calculation unit that calculates a body fat mass based on said body impedance measured by said body impedance measurement unit;
• a fitting belt for bringing said back area electrodes into contact with the surface of the back area of the measurement subject in a pressurized state by being tightened around the trunk area of the measurement subject;
• and
• an upper limb unit comprising a gripping portion that can be gripped by a hand of the measurement subject, said upper limb electrodes being provided in said gripping portion,
• wherein said upper limb unit can be attached to and detached from said fitting belt,
• wherein the fitting belt comprises a buckle portion having a light-transmissive window portion,
• wherein, when the fitting belt is tightened around the trunk area of the measurement subject, the fitting belt measures a circumferential length of the trunk area of the measurement subject,
• wherein a surface of the light-transmissive window portion has a marker, and
• wherein the light-transmissive window allows the measurement subject to visually check whether a position of a navel of the measurement subject matches a position of the marker.
