Patent ID: 6847746

Claim:
An optical waveguide type microplate comprising: a substrate; a frame integrally having at least one partition inside said frame and disposed on the substrate, said frame and said at least one partition defining a plurality of wells, the plurality of wells receiving a solution to be tested; an optical waveguide layer formed on at least a portion of a surface of the well in contact with the solution; a light incident member formed on a surface near another end portion in a longitudinal direction of the optical waveguide layer; and a light exit member formed on a surface near another end portion in the longitudinal direction of the optical waveguide layer, wherein the partition defines a notch which is formed in a direction of height in the partition where each well is positioned, and through which a needle of an automatic sampler is inserted, and a recess is formed in a portion of a surface layer of the substrate, which is immediately below the notch.
