Abstract:
A gas adsorption sheet comprising:a granular activated carbon-containing sheet comprising a granular activated carbon having an average particle diameter of 100 to 600 &mgr;m, a supporting fiber with a fiber diameter of 15 &mgr;m or more for fixing the granular activated carbon in contact with it, and an adhesive fiber which contributes to shape retention and is a water-swelling fiber, wherein the granular activated carbon-containing sheet is integrally formed by wet bonding and has a first surface zone containing supporting fibers and no granular activated carbon on a first surface, and a granular activated carbon-sedimenting zone on a second surface; and an air-permeable sheet laminated on the second surface.
