PROBLEM TO BE SOLVED: To improve an interlaminar adhesive strength of a laminated body for a tire in which a film of a thermoplastic resin composition or a thermoplastic elastomer composition and a laminated body of a rubber composition are vulcanized and thereby are integrated with each other.SOLUTION: A rubber composition contains: (A) a rubber component containing two or more kinds of rubbers; (B) a condensate of a compound represented by formula (1) (Rto Rare independently selected from hydrogen, a hydroxyl group. an alkyl group having 1 to 8 carbon atoms and an ether group having 1 to 8 carbon atoms), and formaldehyde; (C) methylene donor; and (D) a vulcanizer. The rubber component (A) contains 5-15 mass% of an epoxy group-containing rubber, 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
