PROBLEM TO BE SOLVED: To improve dust collecting efficiency and reduce the manufacturing cost of a dustproof mat by superposing an upper layer mat member on a lower layer mat member, arranging many voids penetrating the surface and reverse, on the upper layer mat member and providing adhesiveness to the top of the lower layer mat member. SOLUTION: The dustproof mat 1 is composed of a lower layer mat member 2, and an upper layer mat member 3 overlaid on the top thereof. The upper layer mat member 3 is formed of a plurality of elastic wires formed into coil form, and many voids penetrating the surface and reverse are arranged. In addition, an adhesive material is applied to the top of the lower layer mat member 2 to form a viscous layer 4. Dust sticking to shoe soles is removed by rubbing them against the dustproof mat 1. Among removed dust, large one is captured by the upper layer mat member and fine one is dropped to the lower layer mat member 2 and captured by the adhesive layer 4, thus improving dust collection efficiency and reducing manufacturing cost.
