ABSTRACT:
A mat material includes inorganic fibers, a first surface, and a second surface opposite to the first surface. The mat material has plural needle traces formed by performing a needling treatment. The needle traces extend from the first surface toward the second surface and from the second surface toward the first surface. There is no depth in the mat material that the needle traces do not reach. There is substantially no protrusion of a bundle of the inorganic fibers at a position on the second surface that lies on a line extending from each of the needle traces extending from the first surface. There is substantially no protrusion of a bundle of the inorganic fibers at a position on the first surface that lies on a line extending from each of the needle traces extending from the second surface.
