PROBLEM TO BE SOLVED: To satisfy both improvement of abrasion resistance of a sensor part and reduction in a manufacturing cost, and to improve measurement accuracy in a body moisture meter.SOLUTION: A sensor is constituted of a multilayer structure in which a plurality of printed circuit boards having both a surface and a rear surface on which wiring can be performed are laminated. In the printed circuit board provided on a first tier having a first surface making contact with a body surface of a subject out of the plurality of the laminated printed circuit boards, two comb-shaped electrodes for measuring electrostatic capacitance of the body surface of the subject are arranged on a second surface that is opposite of the first surface in such a manner that respective comb teeth are staggered. The two comb-shaped electrodes respectively have six comb teeth which have a width of 0.2 to 0.8 mm and a length of 4 to 6 mm at intervals of 0.2 to 0.8 mm.COPYRIGHT: (C)2015,JPO&INPIT【課題】 体内水分計において、センサ部の耐摩耗性の向上と製造コストの低減を両立させるとともに、測定精度の向上を図る。【解決手段】 表裏に配線可能なプリント基板が複数積層された多層構造によって構成されたセンサであって、前記複数積層されたプリント基板のうち、被検者の体表面に接触する第1の面を有する第1の段に配されたプリント基板は、該第1の面と反対側の第2の面に、被検者の体表面の静電容量を測定するための2つの櫛形の電極が、それぞれの櫛歯が互い違いになるように配置されており、かつ、前記2つの櫛形の電極は、それぞれ、幅が0.2mm~0.8mm、長さが4mm~6mmの櫛歯が、0.2mm~0.8mmの間隔で6本配されてなることを特徴とする。【選択図】 図4
