PROBLEM TO BE SOLVED: To accurately measure subcutaneous fat thickness by minimizing deformation of tissue caused when an electrode is pressed against the body.SOLUTION: When the state where resistance R is smaller than 100 &Omega (S13), reactance X is smaller than 15 &Omega (S14) and a ratio R/X is smaller than 30 (S15) continues for three times, the third measured value is defined as a reference value (S18-S20). When the state where the amounts of change and rates of changes from the reference values are within a range of a predetermined appropriate value (S27-S29) continues for three times (S30), the subcutaneous fat thickness is calculated using the average value of the resistance R and the reactance X (S31).COPYRIGHT: (C)2012,JPO&INPIT【課題】電極の押し当てによって生じる組織の変形を最小限に抑えて皮下脂肪厚を精度良く測定する。【解決手段】レジスタンスRが100Ω未満(S13)、リアクタンスXが15Ω未満(S14)、および比R/Xが30未満(S15)の状態が3回続いた時に3回目の各計測値を基準値する(S18~S20)。基準値からのそれぞれの変動量、変動率が所定の適正値の範囲内(S27~S29)の状態が3回続いた時に(S30)、レジスタンスRとリアクタンスXの平均値を用いて皮下脂肪厚を算出する(S31)。【選択図】図10
