A biosensor and a method for manufacturing the biosensor. The biosensor comprises an insulating base board (1), an electrode system (2, 3, and 4), a reagent, and an insulation layer (5). The insulation layer (5) covers a part of the electrode system (2, 3, and 4). Also, an enclosed area (6) without the insulation layer is formed at where the reagent is. The enclosed area (6) is provided with an enclosing border having no sharp corner. The reagent covers the enclosed area (6) and does not go beyond the enclosing border. The biosensor also comprises an auxiliary diffusion electrode (12). The use of the enclosing border having no sharp corner and of the auxiliary diffusion electrode (12) reduces the edge effect of the reagent, allows the reagent to diffuse uniformly at response areas of the electrodes, effectively controls the amount of reagent used, reduces product costs, and allows for simple manufacturing. |
