A cartridge adaptable to various measurement forms is provided. A sample is injected into a well (21) via an injection path (24). When a roller (6) while kept pressed into contact with the cartridge is rotated rightward, the sample held in the well (21), and liquid solvent held in a well (22) are caused to reach a well (23) via flow paths (25, 26), respectively thereby mixing the sample with the liquid solvent. A mixed liquid is branched into flow paths (27, 28, 29), respectively, to thereby reach wells (31, 32, 33), respectively, and reagents pre-held in wells (31a, 32a, 33a), respectively, are caused to flow into the wells (31, 32, 33), respectively Next, temperatures in the wells (31, 32, 33), respectively, are controlled, thereby executing DNA amplification. Then, PCR by-products as amplified in the wells (31, 32, 33), respectively, are transferred as far as a position in the vicinity of an electrode (51) via flow paths (41, 42, 43). Subsequently, a voltage is applied across the electrode (51) as a negative electrode, and an electrode (52) as a positive electrode via a drawing electrode (51a) and a drawing electrode (52a), to thereby cause the PCR by-products to undergo electrophoresis. |
