Abstract
A component sensor detects a fluid component with improved accuracy. The component sensor includes tube () including tube side () that permits inflow of fluid (), substrate () provided to tube (), first protrusion () provided at one end of substrate (), second protrusion () provided at another end of substrate (), light emitter () that emits infrared light () toward first protrusion (), and light receiver () that receives infrared light (). Infrared light () entering substrate () through first protrusion () experiences total reflection inside substrate () and exits through second protrusion () to head for light receiver (). Tube side () includes two through holes () that each extend between an interior and an exterior of tube (). Substrate () is inserted into through holes () with a central part of substrate () being inside tube () and with the one end and the other end of substrate () that are respectively provided with first protrusion () and second protrusion () being outside tube ().
