Abstract:
1. A body fat measurement device comprising: multiple electrodes for making contact with predetermined areas of a surface of a measurement subject's body, wherein the multiple electrodes include at least lower limb electrodes for making contact with surfaces of the measurement subject's lower limbs; a body impedance measurement unit that measures a body impedance of the measurement subject's body using the multiple electrodes; a trunk area width detection unit for detecting a trunk area width and a trunk area depth of the measurement subject; and a body fat mass calculation unit programmed to calculate a body fat mass based on the body impedance measured by the body impedance measurement unit and the trunk area width and trunk area depth detected by the trunk area width detection unit, a frame-shaped trunk area width measurement unit in which the trunk area width detection unit is provided and that is capable of being disposed so as to substantially surround four sides of the measurement subject's trunk area, wherein the frame-shaped trunk area width measurement unit defines a hollow opening area into which the measurement subject's trunk area is inserted; a platform unit for bringing the lower limb electrodes into contact with the soles of the measurement subject's feet when the measurement subject steps onto the platform unit, wherein the trunk area width measurement unit can be attached to and removed from the platform unit so as to take on a stored state, in which the trunk area width measurement unit is stored with the platform unit, and an unstored state, in which the trunk area width measurement unit is removed from the platform unit, and at least part of the platform unit is, during the stored state, contained within the hollow opening area of the trunk area width measurement unit.
