PROBLEM TO BE SOLVED: To obtain an analyzer whose disposability and mass productivity are excellent and which is low-cost and small by forming a groove on the surface of an organic polymer flat board, irradiating a liquid inside the groove with exciting light, and measuring a change in physical quantity due to the partial temperature change of the liquid. SOLUTION: An organic polymer flat board 25 in which grooves 17 to 21 for capillary molding are provided on the surface and which is 120 cm long, 80 cm wide and 5 mm thick, is molded, and liquid reservoirs 13 to 16 are formed on the opposite side of the grooves 17 to 21. A resin sheet 26 is pasted onto the flat board 25, interconnections 22 and an electrode 24 are formed, and a capillary device is formed. Then, a buffer solution is dropped into the liquid reservoir 16, and the grooves 17 to 21 are filled with the buffer solution. After that, a reagent is dropped into the liquid reservoirs 14, 15, and a specimen is dropped into the liquid reservoir 13. Then, the capillary device is placed on the stage of an inverter microscope, a voltage is applied to the electrode 24, an electroosmotic flow is generated to the liquid reservoir 16 from the liquid reservoirs 13 to 15, the specimen and the reagent are mixed and reacted in the grooves 17 to 19 so as to be guided to a detection part 23, a laser for excitation is irradiated, and the specimen is detected by a photothermal conversion method.
