Abstract
The purpose of the present invention is to provide an inorganic fiber laminate having improved uniformity of surface density, as well as provide a vacuum insulation material using the same, and a manufacturing method for the same. The present invention relates to an inorganic fiber laminate (10) at least including a first inorganic fiber mat (1) that has a high-surface-density section (1a) and a low-surface-density section (1b), and a second inorganic fiber mat (2) that has a high-surface-density section (2a) and a low-surface-density section (2a), wherein the high-surface-density section (1a, 2a) of the first inorganic fiber mat (1) and/or the second inorganic fiber mat (2) are/is laminated on the low-surface-density section (1b) of the first inorganic fiber mat (1), and the high-surface-density section (1a, 2a) of the first inorganic fiber mat (1) and/or the second inorganic fiber mat are/is laminated on the low-surface-density section (2b) of the second inorganic fiber mat (2).
