PROBLEM TO BE SOLVED: To provide an interliner for laminated glass suitable for forming a laminated glass having excellent principal performance necessary for laminated glass. SOLUTION: The objective interliner is an alternate laminate of (A) a resin layer composed of a polyvinyl acetal resin (a) and a plasticizer (a) and (B) a resin layer composed of a polyvinyl acetal resin (b) and a plasticizer (b) wherein the absolute value (Tab-Tba) of the difference between the cloud point (Tab) of a solution of a mixture of the polyvinyl acetal resin (a) and the plasticizer (b) and the cloud point (Tba) of a solution of a mixture of the polyvinyl acetal resin (b) and the plasticizer (a) is >=50 deg.C and the cloud point (Taa) of a solution of a mixture of the polyvinyl acetal resin (a) and the plasticizer (a) and/or the cloud point (Tbb) of a solution of a mixture of the polyvinyl acetal resin (b) and the plasticizer (b) is <=50 deg.C.
