Abstract
An apparatus for optical measurement is formed as a one-piece molding. The apparatus has a reaction vessel and pre-treatment vessels, at least part of the partitioning wall between the both serves as an optical waveguide body, and a light absorber vessel is formed adjacent the reaction vessel (24). Simplification of the process of manufacture thus is attained. With a light absorber accommodated in the light absorber vessel, (25), reaction components of excitation light and other noise light components that are propagated through the optical waveguide body can be sufficiently attenuated to improve the S/N ratio of the optical measurement.
