An oxygen-absorbing film (1) is composed of an oxygen-absorbing layer (2) and thermoplastic resin layers (3) provided on both surface of the oxygen-absorbing layer (2), wherein the oxygen-absorbing layer (2) comprises both a thermoplastic resin and an oxygen-deficient cerium oxide, and the content of the oxygen-deficient cerium oxide exceeds 50 wt % and is less than 85 wt %. The oxygen-absorbing layer is formed preferably from a resin composition which contains an oxygen-deficient cerium oxide in an amount exceeding 50 wt % and which exhibits a melt flow rate of 1.0 to 18.0 g/10 min.
