Claim Text:
1. A fat mass measurement apparatus for measuring a fat mass in a body based on a body impedance measured by bringing impedance measurement electrodes into contact with a measurement subject's body surface, the apparatus comprising: impedance measurement electrodes configured to come into contact with a measurement subject's body surface; an electrode support unit that supports said impedance measurement electrodes so as to be capable of making contact with the body surface; a position detection means for detecting a predetermined position in a trunk area of the measurement subject; an area detection means for detecting a predetermined area in the trunk area using the position detected by said position detection means; an electrode position setting means for setting, on the body surface at said predetermined area detected by said area detection means, a plurality of positions along a vertical direction of the trunk area for measuring said body impedance; a movement unit that moves said electrode support unit along said vertical direction of the trunk area; an impedance measurement means for measuring said body impedance by bringing said impedance measurement electrodes into contact with each of the plurality of positions set by said electrode position setting means, a fat mass calculation means for calculating a fat mass of said predetermined area based on said body impedances at each of said plurality of positions measured by said impedance measurement means and a size of the trunk area at said predetermined area.
