Abstract
There is provided a biosensor in which a spacerhaving a cutout portion is bonded between at least first supportand a second supportto form a specimen supply paththrough which a supplied specimen is sucked into a space between the supportsand, a reagent that reacts with a component in the specimen is placed in the specimen supply path, and an air holefor promoting suction of the specimen is formed in the second support; wherein the air holeis shaped such that a diameter y of an openingat one surface of the second supportwhich faces the specimen supply pathis larger than a diameter x of an openingat the other surface of the second support, and projecting partsandare formed at the peripheries of the openingsand, respectively. Thereby, a sufficient amount of specimen can be sucked regardless of the viscosity of the specimen supplied to the biosensor, and further, the specimen is prevented from flowing over the air hole
