Abstract:
The present invention provides an assay device wherein manufacturing variations are minimized, a high measurement accuracy of the assay device is maintained, and the liquid-controlling performance is improved. This assay device has a microchannel 2 for channeling a liquid, an absorption porous medium 3 positioned across a gap from one end part 2a of the microchannel 2, a separation space 4 between the microchannel 2 and the absorption porous medium 3, and an accommodation space 5 for accommodating the absorption porous medium 3. The assay device also has a lower member 20 that is an integral molded article constituting a part thereof. The lower member 20 defines the lower part 2b of the microchannel 2, the lower part 4a of the separation space 4, and the lower part 5a of the accommodation space 5. The lower parts 4a, 5a of the separation space 4 and the accommodation space 5 incline downward from the other side to one side with respect to the flow direction. The lower member 20 supports the absorption porous medium 3 at the lower part 5a of the accommodation space 5.
