Then, a porous ceramics carrier for immobilizing the yeast is prepared by sintering to form pores having a fine concavo-convex structure on the surface of the carrier, and when the granulated particles are formed, left and right vibrations are applied to the ring-forming mold to form the surface of the carrier. At the same time to form a fine wrinkles on the surface of the carrier to form a carrier for forming a microstructure of the uneven structure.
