Abstract

An optical measurement apparatus includes a reaction vessel 2 which is formed in one body with a slab-type optical waveguide 1, and the apparatus adds fine-grains or water soluble dye for absorbing a fluorescent light which is radiated from fluorescent dye, and/or an exciting light so that stray light due to reagent is reduced and the S/N ratio of the optical measurement is improved.
