Abstract
An inorganic non-woven fiber sheet has a thickness T of 1 mm or more and contains shots derived from inorganic fibers and having a diameter of 45 μm or more. The shots is distributed as represented by '1−Y/X≤0.11.' Wherein X represents “a total weight of the shots in the inorganic fiber sheet per unit area”/“a total weight of the inorganic fiber sheet per unit area”, and Y represents “a weight of the shots per unit area included in the inorganic fiber sheet from which a portion having a thickness t and satisfying 0≤t≤s is removed, 0.10 mm≤s≤0.55 mm, with a wire side surface as a reference surface”/“a weight per unit area of the inorganic fiber sheet from which the portion having the thickness t is removed with the wire side surface as the reference surface”.
