Abstract
A holding seal material includes inorganic fibers, skin layers provided around the inorganic fibers, inorganic particles included in the skin layers, a first main surface, and a second main surface. Thicknesses of the skin layers satisfy X>Y≧Z. X is a thickness of the skin layer of the inorganic fibers in a vicinity of the first main surface. Y is a thickness of the skin layer of the inorganic fibers in a vicinity of a center of the holding seal material in a thickness direction. Z is a thickness of the skin layer of the inorganic fibers in a vicinity of the second main surface.
