PROBLEM TO BE SOLVED: To easily and accurately measure the body fat percentage of an animal whose skin is covered with hair.SOLUTION: The body fat measuring instrument 10 for animals includes: a pair of insulating electrode bodies 20 arranged side by side on one plane and used by being pressed to a part of the body of the animal a calculation part 30 which is electrically connected to the electrode bodies 20 and applies a voltage between the electrode bodies 20 so as to calculate capacitance between the electrode bodies 20 a computing part 40 for computing body fat from the capacitance calculated in the calculation part 30 and a display part 50 for displaying the result computed in the computing part 40. A gap is provided between the pair of electrode bodies 20 and the gap is fixed.COPYRIGHT: (C)2010,JPO&INPIT【課題】皮膚が被毛で覆われた動物の体脂肪率を簡便かつ正確に測定することができる。【解決手段】動物用体脂肪測定具10は、一つの平面上に並設され、動物の体の一部に押し付けて用いられる一対の絶縁電極体20と、電極体20と電気的に接続し、かつ電極体20間に電圧を印加することで電極体20間の静電容量の算定が可能な算定部30と、算定部30で算定された静電容量から体脂肪を演算する演算部40と、演算部40で演算された結果を表示する表示部50とを具備する。一対の電極体20間に間隙が設けられており、かつ該間隙が固定されている。【選択図】図1
