PURPOSE:To obtain a bonded article having excellent adhesion and resistance to oil and heat, by bonding acrylic rubbers before or after vulcanization through a specified thermoplastic polyester block copolymer by heating. CONSTITUTION:Acrylic rubbers (A) composed of 40-90wt% acrylate of the formula [wherein R is a 1-10C (cyano)alkyl, alkoxyalkyl, etc.], 0.1-30wt% halogen- or epoxy-contg. monomer or polyene monomer and 0-40wt% other vinylidene monomer are bonded through a thermoplastic polyester block copolymer (B) composed of a high-melting polyester segment having an m.p. of 150 deg.C or above and 5-80wt% low-melting segment having a softening point of 80 deg.C or below and an MW of 400-6,000 as an adhesive at 150-250 deg.C under pressure of 50g/cm<3> or above for several sec to several tens of sec.
