PROBLEM TO BE SOLVED: To improve an interlaminar adhesive strength of layers of a thermoplastic composition film and a rubber composition.SOLUTION: There is provided a laminated body for a tire in which layers of a thermoplastic composition film and a rubber composition are vulcanized and thereby are integrated with each other, where the rubber composition contains: (A) a rubber component containing two or more kinds of rubbers; (B) a condensate of a compound represented by formula (1) and formaldehyde; (C) methylene donor; and (D) a vulcanizer. The rubber component (A) contains 5-40 mass% of a rubber having a dicarboxylic acid group and/or a dicarboxylic acid anhydride group in the side chain, 0.5-20 pts.mass of the condensate (B) and 0.25-200 pts.mass of the methylene donor (C) exist with respect to 100 pts.mass of the rubber component (A), and a mass ratio between (C) and (B) is 0.5:1 to 10:1.SELECTED DRAWING: None
