<p>PROBLEM TO BE SOLVED: To provide an analysis element chip in which a defect is difficult to occur in a metal thin film even if the metal thin film is placed under high-humidity environment in order to maintain the activity of a physiologically active substance fixed on the surface of the metal thin film.SOLUTION: A analysis element chip is used for a surface plasmon resonance analyzer or a surface plasmon resonance fluorescence analyzer, and comprises: a prism 11; a metal thin film 15 which is formed on a surface of a predetermined surface 13 of the prism 11 and on a surface 15a of which a physiological active substance 16 is fixed; and a flow channel member 20 which forms a flow channel 21 through which a specimen flows while contacting the metal thin film 15. A half width of a main peak in X-ray diffraction of the metal thin film 15 is 0.353 or less, and the analysis element chip stores the metal thin film 15 in the state where the film is placed under high-humidity environment by preservation liquid is encapsulated in the flow channel 21 or water is reserved on the surface of the metal thin film 15.</p> |
