PROBLEM TO BE SOLVED: To provide a bubble detector for accurately detecting the adhesion of bubbles, and to provide a biogenic substance measuring device having the bubble detector when accurate measurement of liquid temperature becomes difficult since bubbles mixed into and generated in a channel adhere to a temperature measurement means.SOLUTION: The bubble detector includes: a temperature measurement means for measuring the temperature of liquid circulated in a channel a storage means for storing a preset temperature upper-limit value or temperature change rate and a bubble adhesion discrimination means for discriminating the adhesion of bubbles in the temperature measurement means from a temperature measurement result output from the temperature measurement means and the temperature upper-limit value, and from the temperature change rate obtained from the temperature measurement result output from the temperature measurement means and the temperature change rate stored by the temperature storage. The biogenic substance measuring device uses the bubble detector.COPYRIGHT: (C)2010,JPO&INPIT【課題】流路中に混入乃至発生した気泡が測温手段に付着して正確な液体の温度測定が困難になった場合に、気泡の付着を正確に検出する気泡検出装置及び前記気泡検出装置を備えた生体成分測定装置を提供すること。【解決手段】流路内を流通する液体の温度を測定する測温手段、予め設定される温度上限値又は温度変化率を記憶する記憶手段、及び前記測温手段から出力される測温結果と前記温度上限値とに基づいて、又は前記測温手段から出力される測温結果から求められる温度変化率と前記記憶手段が記憶する前記温度変化率とに基づいて前記測温手段における気泡付着を判別する気泡付着判別手段を備えることを特徴とする気泡検出装置及びそれを用いた生体成分測定装置。【選択図】図1
