PROBLEM TO BE SOLVED: To obtain a low-cost laminate which can prevent the back halation generated at the time of simultaneous exposure of both front and rear surfaces with ultraviolet rays by using inorganic fiber woven fabric and to have excellent adhesive properties and uniformity. SOLUTION: This laminate comprises at least one inorganic fiber woven fabric having warps or/and wefts of mineral fiber using basalt as raw material. The mineral fiber is textured yarn, and at least inorganic fiber woven fabric is used as an inner layer. The gap interval of adjacent yarn bundles with respect to the direction of fiber orienting direction of the mineral fiber of the fabric is 200μm or less.
