PROBLEM TO BE SOLVED: To provide an oxygen-absorbing prefilled syringe which can suppress generation of a low molecular weight compound after oxygen absorption, has excellent oxygen barrier performance, maintains strength even in long-term preservation, reduces elution volume of impurity, and has low drug solution adsorptivity, and to provide an oxygen-absorbing prefilled syringe which has excellent oxygen absorption performance under a wide humidity condition from low humidity to high humidity.SOLUTION: A prefilled syringe includes at least three layers in following order: a first resin layer at least containing polyester; an oxygen-absorbing layer composed of copolymerization polyolefin compound and oxygen-absorbing resin composition containing a transition metal catalyst; and a second resin layer at least containing polyester. The copolymerization polyolefin compound contains a constitutional unit having at least one tetralin ring. |
