A resin composition comprises: a modified EVOH (A) that is represented by a following formula (I), has contents (mol%) of a, b, and c based on the total monomer units satisfying following formulae (1) through (3), and has a degree of saponification (DS) defined by a following formula (4) of 90 mol% or more; and inorganic oxide particles (B), wherein a content of the inorganic oxide particles (B) is from 5 to 5000 ppm. Such a resin composition is improved in adhesion to a resin other than EVOH, secondary processability, and flexibility without decreasing the performances originally possessed by EVOH, such as gas barrier properties, transparency, flavor retention, solvent resistance, and oil resistance. Accordingly, the resin is preferably used as a molded article, a film, a sheet, a heat shrinkable film, a thermoformed article, a multilayer structure, a coinjection stretch blow molded container, a fuel container, and the like.18≤a≤550.01≤c≤20100−a+c×0.9≤b≤100−a+cDS=TotalNumberofMolesofHydrogenAtomsinX,Y,andZ/TotalNumberofMolesofX,Y,andZ×100
