In a display section, a measured value of information of a living body is displayed on a measured data display section, and a figure representing a human body including body parts such as arm and leg is displayed on a body display section. For example, a percentage of muscle and a percentage of body fat measured 30 days ago and a current percentage of muscle and percentage of body fat are compared with each other, and respective increase/decrease values are displayed on the measured data display section as well as the measured values. Further, a color of illumination in the background of the body display section is changed depending on a degree of the increase/decrease value. For example, the background of the body display section is illuminated in red when the percentage of muscle is decreased by a % or more, blue when increased by a % or more, and green when a percentage of variation is less than a % in comparing current data with data measured 30 days ago.
