Abstract
A mat material including: inorganic fibers; and an oily fiber-scattering inhibitor attached to a surface of the inorganic fibers, wherein the amount of the fiber-scattering inhibitor attached is 0.05 to 2.0% by weight, and the mat material has an odor index of 80 or less as a relative value determined by an odor sensor from the odor of decomposed gas generated when the mat material is placed on a 500° C. hot plate, when the odor index of a mat material to which 1.0% by weight of an acrylic resin as a fiber-scattering inhibitor is attached is taken as 130.
