A manufacturing method of spot block is provided to form air gap automatically at a curing process after materials are combined using water-soluble capsule and dry ice and to suppress generation of crack although loess ingredient is added. A manufacturing method of spot block comprises steps of: mixing a plurality of dry ice particles(55) with infrared radiation material(50); containing mixed materials inside a plurality of water-soluble capsules(40); mixing a water-soluble capsule in which infrared radiation material and dry ice particle are contained with other materials comprising block(10); and injecting the mixed materials in a mold, adding pressure and forming the block. |
