A microfluidic chip used in latex agglutination for analyzing a small amount of liquid specimen with a latex reagent is provided, in order to suppress adsorption of latex particles into an inner wall surface of a latex reagent retaining chamber of the microfluidic chip, and to improve measuring precision of the latex agglutination. The microfluidic chip includes a retaining chamber for the latex reagent, wherein an absolute value of a surface zeta potential in at least one inner wall surface of the retaining chamber is at least 20 mV.
