PROBLEM TO BE SOLVED: To provide a subcutaneous fat thickness measuring device, specifying a measuring site, and eliminating the pressing operation by confirming and selecting a measurement start button for each measuring site.SOLUTION: The subcutaneous fat thickness measuring device includes: a light emitting part 11 a first light receiving part 12A a second light receiving part 12B and a measuring site specifying means having a set site determination means. The set site determination means compares first light receiving amount data obtained by the first light receiving part with second light receiving amount data obtained by the second light receiving part. When the first light receiving amount is larger than the second light receiving mount, the measuring site is determined to be a thigh or an arm, and when not larger, the measuring site is determined to be an abdomen.COPYRIGHT: (C)2010,JPO&INPIT【課題】測定部位を特定でき、測定部位ごとに測定開始ボタンを確認し選択して押圧操作する必要のない皮下脂肪厚測定装置の提供を目的とする。【解決手段】発光部11と、第1受光部12Aと、第2受光部12Bと、設定部位判定手段を有する測定部位特定手段とを備える。設定部位判定手段は、第1受光部によって得られた第1受光量データと第2受光部により得られた第2受光量データと対比し、第1受光量が第2受光量よりも多い場合に、測定部位が太もも又は腕であるとの判定を行い、多くない場合に、測定部位が腹部であるとの判定を行う。【選択図】図2
