To provide a body composition meter retaining a measurement accuracy in a bioelectric impedance measurement, having storage performance and capable of calculating indices related to the body composition of an organism.

This meter, in its upper face, is provided with electrode for the feet with which the soles of a subject come into contact, and two left/right hand grips connected from the left/right of a casing with cords are provided with electrodes. The inside of the casing is provided with cord reels for rewinding the cords. The cord reel uses a spiral spring and tensile force is constantly operated to automatically rewind the cord. The cords for connecting the casing to the hand grips are connected to an approximately central position of the axial direction of the hand grips.
