An oxygen-absorbing container includes a container body having a multilayer structure constituted by an innermost layer, an outermost layer and an intermediate layer therebetween, the container body having an opening part on an upper part thereof； and a sealing member bonded to an upper end surface of the opening part of the container body to seal an opening of the opening part. The innermost layer and the intermediate layer are bent outward at an upper end of the opening part and form a flat part and a surface of the flat part forms the upper end surface of the opening part. When the sealing member is unsealed, part of the innermost layer on the upper end surface of the opening part is configured to be peeled off so as to leave an unsealed mark.
