PROBLEM TO BE SOLVED: To provide an interlayer for glass laminates which has a high tensile strength and is resistant to fracture in use.SOLUTION: In an interlayer 1 for glass laminates has a structure composed of one layer, two or more layers or five or more layers, at least one thermoplastic resin layer 11 containing a thermoplastic resin is provided, and the thermoplastic resin is a polyvinyl acetal resin or an ethylene-vinyl acetate copolymer and has a double refraction ΔNxy of 0.00035 or higher. The thermoplastic resin layer 11 is laminated in the thickness direction.
