PURPOSE:To provide laminated glass which has excellent water resistance, impact resistance, transparency, adhesive workability, etc., and is suitable for a windshield of an automobile, etc., by laminating glass sheets to each other via thin sheets of a specifically composed ethylenic multi-element copolymer interposed therebetween. CONSTITUTION:The ethylenic multi-element copolymer consisting of (A) 50-99.98mol% ethylene, (B) 20-0.01mol% unsatd. dicarboxylic acid (anhydride) of 4-30C, (e.g.: maleic acid) and (or) the half ester thereof, and (C) 30-0.01mol% unsatd. carboxylate of <=30C, (e.g.: methyl acrylate) and (or) vinyl ester of <=30C (e.g.: vinyl acetate) is produced. The glass sheets are laminated on each other via the thin sheets of the above-mentioned copolymer interposed therebetween to obtain the intended laminated glass. The copolymer contg. the dicarboxylic group among the above-mentioned multi-element copolymers may be used by half esterifying the dicarboxylic acid incorporated therein.
