Abstract: A device including a well array including wells in which a target substance is detected based on a biochemical reaction thereof. Each of the wells has an aspect ratio of 1 or more as calculated by Formula (1) such that the biochemical reaction of the target substance is detected, Aspect ratio=Depth of each well/Diameter of largest circle among circles included in a region enclosed by a rim of each well  Formula (1).

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.

Abstract: A reaction container including a transparent base having a first surface having at least one region where recessed portions are formed and recessed from the first surface, and a cover member positioned such that the cover member forms a gap from the first surface inside the region and is welded to the transparent base outside the region. The cover member absorbs infrared light and transmits light having a wavelength within a range of visible light.
