Abstract:
1. A mat comprising: inorganic fibers; a first main surface; a second main surface; a first interlaced part group including a plurality of first interlaced parts arranged in rows along the first main surface, each of the plurality of first interlaced ports being constituted by interlacing the inorganic fibers with one another and formed from a starting point on the first main surface to a finishing point present between the first main surface and the second main surface, the plurality of first interlaced parts within each row of the first interlaced group being not arranged on substantially straight lines, all of the plurality of first interlaced parts within each row of the first interlaced part group being provided within respective first stripe regions each having a width of 6 mm, each first stripe region of the first stripe regions being spaced apart by a first open region from each adjacent first stripe region of the first stripe regions such that no first interlaced parts of the plurality of first interlaced parts are provided in the first oven region; a second interlaced part group including a plurality of second interlaced parts arranged in rows alone the second main surface, each of the plurality of second interlaced parts being constituted by interlacing the inorganic fibers with one another and formed from a starting point on the second main surface to a finishing point present between the first main surface and the second main surface, the plurality of second interlaced parts within each row of the second interlaced group being not arranged on substantially straight lines, all of the plurality of second interlaced parts within each row of the second interlaced part group being provided within respective second stripe regions each having a width of 6 mm, each second stripe region of the second stripe regions being spaced apart by a second open region from each adjacent second stripe region of the second stripe regions such that no second interlaced parts of the plurality of second interlaced parts are provided in the second open region; and a direction of rows formed by the first interlaced part group along the first main surface and a direction of rows formed by the second interlaced part group along the second main surface being different from each other, wherein an angle formed between the direction of the rows formed by the first interlaced part group and the direction of the rows formed by the second interlaced part group is from about 60° to about 90° when viewed in a thickness direction of the mat.
