PROBLEM TO BE SOLVED: To eliminate the need for a secondary sealing material and to reduce the cost in the plural-layer glass formed by opposing plural glass sheets to one another to form a hollow layer with a spacer in between by forming the spacer from a specified thermoplastic resin composition. SOLUTION: The spacer 20 is formed from a thermoplastic resin composition contg. 50-98wt.% butyl rubber (e.g. partially cross-linked butyl rubber) and 2-50wt.% crystalline polyolefin (e.g. high-density PE) (100wt.% in total) and further contg., as required, >=200 pts.wt. of an inorg. filler (e.g. talc) based on 100 pts.wt. of the butyl rubber and crystalline polyolefin. The steam permeability coefficient of the crystalline polyolefin and/or butyl rubber is preferably controlled to <=3,000×10<-13> cm<3> .cm/cm<2> .sec.Pa and/or that of the thermoplastic resin composition to <=5,000×10<-13> cm<3> .cm/cm<2> .sec.Pa. |
