Disclosed are: a saponified ethylene/vinyl ester copolymer (EVOH) resin composition which exhibits, even at high temperature, excellent discoloration resistance and excellent heat resistance and which has excellent adhesiveness to a thermoplastic resin composition and can provide a multilayer structure having excellent surface appearance; and a multilayer structure that contains a layer of the composition. The EVOH resin composition comprises (A) an EVOH resin, (B) an alkaline earth metal, (C) an alkali metal, and (D) a carboxylic acid having 2 to 4 carbon atoms, and satisfies the following requirements (α) to (γ): (α) the content of the alkaline earth metal (B) relative to the EVOH resin (A) exceeds 10ppm and is up to 50ppm; (β) the content ratio (C/B) of the alkali metal (C) to the alkaline earth metal (B) is 0.001 to 0.5; and (γ) the content ratio (D/B) of the carboxylic acid (D) to the alkaline earth metal (B) is 5 to 30. |
