Abstract: A reaction container includes a transparent base including a resin material and having recessed portions formed in one or more regions of the transparent base such that the recessed portions are recessed from a surface of the transparent base, and a cover member including a thermoplastic resin material and positioned on the transparent base such that the cover member forms a flow path including a gap extending over the recessed portions between the cover member and the surface of the transparent base and has a spacer portion welded by laser irradiation to the transparent base outside the one or more regions of the transparent base. The cover member absorbs infrared light and transmits light having a wavelength within a range of visible light such that the cover member has light transmittance in the range of from 480 nm to 570 nm.

Abstract: An analysis apparatus including a stage, an analysis device placed on the stage and including receiving sections which accommodate a sample and a reagent for biochemical reaction, and are communicated with one another through a flow path having an inlet and an outlet, a liquid introduction section which is connected to the inlet and supplies into the flow path the sample, the reagent, and an sealing liquid for sealing each of the receiving sections, and a waste liquid storage section which is connected to the outlet and stores as waste liquid an excess of the sample and the reagent and a part of the sealing liquid supplied to the flow path, an optical system which includes an objective lens, emits excitation light to the receiving sections and allows observation of fluorescence generated in the receiving sections by the excitation light, and a control unit that controls such that the sealing liquid and the excess of the sample and the reagent form an interface in the waste liquid storage section, and that the interface is formed at a distance not less than a fluorescence-obtainable distance from a bottom of the receiving sections.
