PURPOSE:To increase an effective period of mothproofing and mildewproofing performance by a method wherein a powdery material with which a drug having mothproofing and mildeproofing properties is brought into wrapping contact is sprayed or applied on the surface of a tatami mat on the surface of which a tatami mat core formed of straw and synthetic foamed resin is sewn. CONSTITUTION:An insulation board forms an upper layer, a rock wool board forms a middle layer, and a lower layer forms a synthetic resin layer. 25g/m of annular oligosaccharide with which 25 pts an antibacterial agent having mothproofing and mildewproofing properties, based on 100 pts cyclodextrin, is wrapped is sprayed on the surface of the middle layer, and a tatami mat surface is sewn to a tatami mat core. Wrapping contact ability of the annular oligosaccharide is utilized for a powdery material with which a mothproofing agent and a mildewproofing agent are brought into wrapping contact, and a drug having mothproofing and mildewproofing properties or a drug having performance as a mothproofing agent and a mildewproofing agent is wrapped therein. A powdery material brought into wrapping contact with the mothproofing agent and the mildewproofing agent is sprayed or applied on the surface of the constituting material of the tatami mat core. This constitution provides a step-on feeling having excellent heat resistance and damping properties.
