PROBLEM TO BE SOLVED: To provide a weight/body composition meter capable of enhancing the accuracy in detection by reducing the influence of bending of a housing.SOLUTION: The weight/body composition meter comprises the housing with a loaded surface on which a subject is placed on the upper surface, supported by a plurality of leg parts on the lower surface electrodes mounted on the loaded surface for measuring the body impedance of the subject load sensors attached to the leg parts for measuring the weight of the subject and an electronic circuit board 19 housed inside the housing and connected to the electrodes and the load sensors via lead wires. The electronic circuit board 19 has an amplification circuit for amplifying input signals from the electrodes and load sensors and outputting the amplified signals to a control circuit. The electronic circuit board 19 is mounted inside the housing in such a way that the board surface is extended approximately in the same direction as the direction of bending of the housing inner wall surface when the loaded surface receives loads.COPYRIGHT: (C)2010,JPO&INPIT【課題】ハウジングのたわみの影響を低減して検出精度の向上を図ることができる体重体組成計を提供する。【解決手段】被検者を載せる被荷重面を上面に備え、下面に設けられた複数の脚部によって支えられるハウジングと、被荷重面に取り付けられて被検者の身体インピーダンスを測定する電極と、脚部に取り付けられて被検者の体重を測定する荷重センサと、ハウジング内部に収容されるとともに電極及び前記荷重センサとリード線を介して接続され、電極及び荷重センサからの入力信号を増幅して制御回路に出力する増幅回路を備える電子回路基板19と、を備える体重体組成計であって、電子回路基板19を、基板の面の延びる向きが、被荷重面に荷重を受けたときにハウジング内壁面がたわむ方向と略同じ方向となるように、ハウジング内部に取り付けたことを特徴とする。【選択図】図5
