There is provided a fuel cell whose current density and maintenance ratio can be improved when at least glucose dehydrogenase and diaphorase are immobilized on an anode using an immobilizing material composed of poly-L-lysine and glutaraldehyde. The fuel cell has a structure in which a cathode 2 and an anode 1 face each other with an electrolyte layer 3 therebetween, the anode 1 being obtained by immobilizing at least glucose dehydrogenase and diaphorase on an electrode using an immobilizing material composed of poly-L-lysine and glutaraldehyde, wherein the mass ratio of the poly-L-lysine to the glutaraldehyde in an immobilizing material is 5:1 to 80:1, the mass ratio of the glucose dehydrogenase to the diaphorase is 1:3 to 200:1, and the average molecular weight of the poly-L-lysine is 21500 or more.
