PROBLEM TO BE SOLVED: To provide a colorimetric analyzer for accurately measuring. SOLUTION: The colorimetric analyzer has a cylindrical body having a reflection face on an inner face and covering a light path of an incoming light to a measured sample. In the apparatus of the invention, a light path of an outgoing light from the measured sample is also covered with the cylindrical body having the reflection face on the inner face. It is preferable that a light source is a light emitting diode and a photodetector is a CdS element. COPYRIGHT: (C)2006,JPO&NCIPI
