PURPOSE:To obtain an excellent alpha-ray shielding film by forming a heat-resisting adhesive layer on a heat-resisting organic film base material and forming a composite body, the total of thickness thereof reaches a specific value or more. CONSTITUTION:The heat-resisting adhesive layer is formed on the heat-resisting organic film base material, and the composite body, the total of thickness thereof reaches 30mum or more, is formed. Each material of a polyimide group, a fluorine group, a silicon group, a polysulfone group, a polyether sulfone group, a polyester group, a polyamide imide group, a polyamide group, etc. is used as the film base material and each material of a silicon group, a fluorine group, a polyamide group, an epoxy group, a polyimide group, a polyamide imide group, a phenol group, etc. as heat-resisting adhesives. alpha-Rays can be shielded only to a necessary section in the adhesive sheet of such constitution, and the sheet can be pasted even in any process. |
