Holding sealing material, method for manufacturing holding sealing material, and exhaust gas purifying apparatus

Abstract

It is an object of the present invention to provide a holding sealing material (10) that can effectively prevent displacement in a width direction of each mat (11,21) upon handling, can maintain high holding force of an exhaust gas treating body upon use as an exhaust gas purifying apparatus, and can prevent leakage of exhaust gases. A holding sealing material (10) comprises: a plurality of mats (11,21) comprising inorganic fibers and having a rectangular shape in a plan view, the plurality of mats being laminated, wherein a length (L2) of a lower one of the plurality of mats in its longitudinal direction is longer than a length (L1) of an upper one of the plurality of mats (11,21) in its longitudinal direction upon the upper one of the plurality of mats being laminated on the lower one of the plurality of mats, the plurality of mats (11,21) are fixed to each other by a fixed portion (30) that exists along a width direction perpendicular to the longitudinal direction of the mats (11,21), both end portions of the fixed portion are spaced apart from a longer side face of the mat.
