The present invention provides a strip for measuring biomaterial, as a strip-type platform for use in a field inspection device. The strip is a porous matrix comprising micropores, and a copolymer selected from the group consisting of polysulfone, polyethersulfone, and polyarylsulfone, in order to increase separation efficiency of the blood cells contained in a sample and to improve accuracy and reproducibility of measurements with a small amount of blood, wherein the matrix comprises an enzyme reacting with the biomaterial, a dye, and a hydrophilic polymer material, and the matrix is brought into contact with the sample containing the biomaterial in the upper layer to measure the biomaterial contained in the sample, diffusing into the lower layer of the matrix, from the color development of the matrix.
