    • An object of the present invention is to provide a mat (1) which has high shearing strength, an appropriately low volume, and high flexibility, which is produced at low cost, and which is excellent in handleability upon wrapping and is less likely to suffer creases upon stuffing in the case that the mat (1) is processed into a holding sealing material. The mat (1) of the present invention comprises inorganic fibrous substances intertwined with each other. The mat (1) comprises: a first main face (10a), a second main face (10b) opposite to the first main face (10a), at least two layers, and an intertwined portion. The at least two layers includes: a first layer (14a) occupying a certain area from the first main face (10a) along a thickness direction of the mat (1), the first layer (14a) comprising a first long fibrous substance (15a) which comprises an inorganic fibrous substance, and a second layer (14b) adjacent to the first layer (14a), the second layer (14b) comprising a short fibrous substance (15b) which comprises an inorganic fibrous substance and which has an average fiber length shorter than an average fiber length of the first long fibrous substance (15a). The intertwined portion (12) extends from the first main face to the second main face (10a). The intertwined portion (12) comprises the first long fibrous substance (15a) and the short fibrous substance (15b) being more closely intertwined with each other than the inorganic fibrous substances in a portion except the intertwined portion.
    • 本发明的目的是提供一种具有高剪切强度,适当低体积和高柔性的垫(1),其以低成本生产,并且在包装时的可操作性优异并且不太可能遭受 在将垫(1)加工成保持密封材料的情况下,填充时会产生折痕。 本发明的垫(1)包含彼此缠结的无机纤维状物质。 垫(1)包括:第一主面(10a),与第一主面(10a)相对的第二主面(10b),至少两层,以及缠绕部。 所述至少两层包括:沿所述垫(1)的厚度方向占据所述第一主面(10a)的一定面积的第一层(14a),所述第一层(14a)包括第一长纤维状物质 )和与第一层(14a)相邻的第二层(14b),第二层(14b)包括短纤维物质(15b),其包含无机纤维物质,并且具有平均纤维 长度短于第一长纤维物质(15a)的平均纤维长度。 交织部分(12)从第一主面延伸到第二主面(10a)。 相互交织的部分(12)包括第一长纤维物质(15a)和短纤维物质(15b),除了交织部分之外的部分中的无机纤维物质彼此之间相互紧密缠结。
