PURPOSE: A body fluid assay cartridge and an electrode structure therefor are provided to stably couple a fixed antibody used for detecting a terrestrial material to an electrode. CONSTITUTION: An electrode structure for a body fluid assay cartridge comprises an electrode(36), a fixed antibody(84), and a fixed polymer(100). The fixed polymer has first, second, and third monomers(102,104,106). The first monomer has a first functional group coupled to the electrode. The second monomer has a second functional group selectively coupled to the fixed antibody. The third monomer has a third functional group for preventing different protein from being absorbed in electrode.
