A body composition detection apparatus (1) is provided. The body composition detection apparatus includes an electrode pair (30) for applying current, and a plurality of electrode voltage pair (40A~40E) for detecting voltages at a plurality of detection points. A control part (50) detects body fat based on voltages detected by the plurality of electrode voltage pair (40A~40E). Voltages of the plurality of points are integral by the control part (50) to get the amount of the body fat.一種體組成測定裝置(1)，其具備施加電流的電流電極對(30)；測定複數個測定點的電壓的複數個電壓電極對(40A～40E)。控制部(50)係基於經由電壓電極對(40A～40E)測定的複數個測定點的測定電壓，測定體脂肪。控制部(50)係利用複數個測定點的測定電壓進行積分，基於其結果計算體脂肪量。
