Abstract
An oxygen absorber for blending in a resin, comprising a mixed powder containing an iron powder, a metal halide and an alkaline substance, and having a half-peak width on a plane (110) of 0.20°/2θ (Co—Kα) or less as measured by a powder X-ray diffraction method, a specific surface area of 0.5 m/g or more, and an average particle size of 1 to 40 μm. The oxygen absorber effectively suppresses the generation of hydrogen, features excellent safety, exhibits excellent oxygen-absorbing capability and offers an advantage of high productivity due to the suppressed occurrence of coarse particles in the step of producing the oxygen absorber.
