Abstract
A testing chip includes (1) a first chip having a micro flow path that stores reagent; upstream-side opening provided on upstream-side of the micro flow path; downstream-side opening provided on downstream-side of the micro flow path; and one or more sealing members in a small thickness stuck to at least one surface of the first chip to seal the upstream-side opening and the downstream-side opening until the testing chip is used and (2) a second chip having a micro flow path for mixing and reaction between reagent and a specimen and detecting the reaction; and an opening provided on upstream-side of the micro flow path, wherein, when the testing chip is used, the first and second chips are superimposed on each other so that the downstream-side opening of the first chip and the opening of the second chip are positioned on each other.
