PROBLEM TO BE SOLVED: To put damage of metallic vapor deposition films due to creases and flaws in the shade by adhering the metallic vapor deposition films to both front and rear surface of a sheet. SOLUTION: Metallic vapor deposition films 2 are adhered to both front and rear surfaces of a material 1 of a sheet. Damage of the metallic vapor deposition films 2 decreases when the metallic vapor deposition films 2 are protected by transparently protecting films 3. If thin cloth materials as the material 1 are used, it is possible to easily carry and fold it while holding strength caused at the time of using a tent and a tarp tent. Incident light 5 does not permeated if the part is different when damage 4 is caused on the metallic deposition films 2. Since identification of reflected light and transmitted light 6 in the rear surface is hard even when the transmitted light 6 goes out by causing the damage 4 of two metallic deposition films 2 in the same part, user does not notice the damage easily. Accordingly, it is put the damage by a bend, etc., in the shade even when the thin material wherein handling is easy is used, so that marketability can be kept when using it for the tent and the tarp tent.
