A bioelectricity impedance measuring device, a malnutrition measurement system, a malnutrition measuring method

A bioelectricity impedance measuring device which measures malnutrition simply is provided. The bioelectricity impedance measuring device comprises a contact surface put to one part of the body, gripper, and electrodes of a contact surface. In addition, the bioelectricity impedance measuring device further comprises a malnutrition measuring means which measures malnutrition is provided. A malnutrition measuring means measures Phase angle theta and/or a RcXc ratio, and measures a nutrient state. A malnutrition measuring means judges a state of malnutrition from a value of Phase angle theta. It is available to display a judged result with a bar classified by display method by color. In addition, it can have further a muscular volume measuring method which measures muscular volume, and this muscular volume measuring method can measure muscular volume also to a child aged 5 and below or an old man aged 60 and over.
