Abstract
In an oxygen absorbent packet, an oxygen absorbent containing moisture is received in the cup like plastic container and an air-permeable layer made of paper is adhered to the opening section of the container. A substantially air-impermeable layer is formed on the outer surface of the air-permeable layer, whereby the oxygen absorbent absorbs oxygen through the peripheral side edge of the air-permeable layer.
