Zusammenfassung:	PURPOSE:To improve dispersion of sulfuric ions and prevent falling-off of active substance by fused-forming a thermoplastic rib mainly made or thermoplastic resin so that the total thickness of a glass mat and the rib can be made uniform. CONSTITUTION:A thermoplastic rib mainly made of the mixture of ethylene- vinyl acetate copolymer resin, stactic polypropylene resin etc. is fused-formed onto a glass mat so that the total thickness of the mat and the rub is made nearly uniform. Therefore, the dispersion of thickness of the glass mat can be absorbed by the rib, and a glass mat equipped with a variety of rib can be obtained easily by varying the thickness of the rib.
