A microchamber array device having built-in reaction microchambers, in which the dilution ratio can be greatly increased at the same time as dramatically raising cell recovery efficiency, and an inspection object analysis method using said device are provided. This microchamber array device is provided with: a microchamber arrayfor cell capture by electrophoresis comprising an arrangement of a substrate, electrodesand photoresists; and a reaction microchamber arraywhich is separated from the capture microchamber array, and which is formed from reaction microchambercomprising micro channelsarranged so as to be opposite of the aforementioned microchamber array

Microchamber array device and method of analyzing inspection object using same

There are provided a detector and a detection method capable of detecting a biological sample with high sensitivity. A detector is provided with a microchamber array including a plurality of storage sections to be filled with a hydrophilic solvent containing a biological sample; and an image sensor in which picture elements are disposed corresponding to the storage sections, wherein the microchamber array includes a flow channel in communication with openings of the storage sections; a hydrophobic solvent supply unit arranged in continuity with the flow channel; and a through-hole which allows the hydrophilic solvent to enter and exit the flow channel, and the hydrophobic solvent supply unit flows a hydrophobic solvent into the flow channel by an externally-applied force.
