PROBLEM TO BE SOLVED: To provide a novel oxygen absorbing prefilled syringe, suppressing the generation of a low-molecular weight compound after oxygen absorption, having excellent oxygen barrier performance, keeping the strength even in a long-term preservation, and decreasing the elution volume of impurity, and to provide an oxygen absorbing prefilled syringe having excellent oxygen absorbing performance under a wide range humidity condition from a low humidity to a high humidity.SOLUTION: An oxygen absorbing prefilled syringe includes at least three layers: an oxygen absorbing layer (a layer A) formed of oxygen absorbing resin composition containing a polyester compound and a transition metal catalyst; and resin layers (layers B) containing a thermoplastic resin laminated on both sides of the layer A, respectively. The polyester compound contains a constitutional unit having at least one tetralin ring. |
