To provide a toilet seat composition meter capable of more accurately measuring composition of a body part by applying an electrode plate for body composition measurement to the buttocks.An electrode plate is attached to an upper surface of a toilet seat 1, a space is provided inside the toilet seat 1, and an electronic circuit board 5 and a load sensor 9 for measuring a body composition are built therein.Since the toilet seat composition meter according to the present invention is installed on a toilet seat and a weak electric current flows from the buttocks, electric current flows directly to the trunk part without going through the legs, so body fat and muscle of only the body part are highly accurate Measurement can be performed. Also, since the body composition meter and the toilet seat are integrated, there is an advantage that it eliminates the trouble of storing it somewhere when using it like a conventional body composition meter, and putting it out when using it.(FIG.【課題】体組成計測のための電極板を臀部に当てることで、より正確に胴体部分の組成計測を行うことができる便座式体組成計を提供する。【解決手段】便座1の上面に電極板を取り付け、便座1内部に空間を設け、その内部に体組成の計測のための電子回路基板5や荷重センサー9を内蔵した。本考案による便座式体組成計は、便座に設置し、臀部から微弱な電流を流すことで、脚を経ることなく直接胴体部分に電流が流れるので胴体部分のみの体脂肪や筋肉の精度の高い計測を行うことができる。また、体組成計と便座が一体化していることで、従来の体組成計のように使い終わったらどこかに収納したり、また使うとき出したりという手間を除くという利点もある。【選択図】図2
