Abstract
An inorganic fiber-formed article, composed of a mat-shaped inorganic fiber assembly, the inorganic fiber-formed article including needle marks that extend in a direction including a thickness direction of the mat-shaped inorganic fiber assembly, where the needle marks include needle marks A and needle marks B having a diameter smaller than that of the needle marks A, dense portions in which a plurality of the needle marks A lie densely are arranged apart, non-dense portions in which a needle mark density of the needle marks A is lower than that in the dense portions are present between the dense portions in both a first direction which is any mat-surface direction extending through the dense portions and a second direction orthogonal to the first direction, and the needle marks B are present at least in the non-dense portions.
