Abstract

A holding seal material made of a laminated mat configured by laminating a plurality of mats containing an inorganic fiber and having a rectangular planar shape so that longitudinal-direction lengths of the respective mats sequentially increase as the mats are laminated, in which the film is attached to a principal surface of the mat configuring the laminated mat and having a longest longitudinal-direction length on an opposite side to a side on which the mat having the longest longitudinal-direction length is in contact with other mats and longitudinal-direction side surfaces of the mat having the longest longitudinal-direction length, and the film is attached to a principal surface of the mat having the longest longitudinal-direction length on the side on which the mat having the longest longitudinal-direction length is in contact with other mats in a state in which a part of the principal surface is exposed.
