<p>It is an object of the present invention to provide a holding sealing material (10) that can maintain high holding strength even after a long term use, when applied to an exhaust gas purifying apparatus for use in a urea SCR system. A holding sealing material (10) having a mat shape, comprising: an adsorption portion (11) configured to adsorb urea and having a width (W) and a longer side face (L) extending along a longitudinal direction of the holding sealing material (10); a holding portion (12) configured to hold an exhaust gas treating body and having another width (K) and another longer side face extending along the longitudinal direction, the width (H) of the adsorption portion (11) being smaller than the another width (K) of the holding portion (12), the longer side face facing the another longer side face via a space (16); and a coupling portion (15a,15b) connecting the adsorption portion (11) and the holding portion (12).</p> |
