Abstract
A holding material for a pollution control element which can sufficiently suppress scattering of inorganic fibers when the pollution control element is assembled in a casing, and which has a sufficiently high coefficient of friction. The holding material includes: a sheet-like main body made of first inorganic fibers having a minor axis in the range of from about 3 to 10 μm; and a surface layer which is provided on at least one surface of the main body and contains second inorganic fibers having a minor axis in the range of from about 1 to 15 nm.
