Disclosed is a dividable apparatus for measuring living body impedance in which a first housing section 22 having a first current feeding electrode 4 and a first measurement electrode 5 mounted thereon can be physically separated from a second housing section 3 having a second current feeding electrode 6 and a second measurement electrode 7 mounted thereon, but said first and second housing sections 22, 3 are kept electrically connected to each other via an electric cable 11, whereby said first and second housing sections 22, 3 can freely be positioned on any parts of the body for impedance measurement. |
