A packaging material (1) of a cone-shaped projection sheet has a cone-shaped projection sheet (23), a sheet (7) for cone-shaped projection molding, and a sealing sheet (9). The cone-shaped projection sheet (23) has a base body (23a), and plural cone-shaped projections (23b) formed upon a surface (23c) of the base body (23a). Sheet (7) for cone-shaped projection molding is used for forming the plural cone-shaped projections (23b) and has plural cone-shaped recesses (33a) disposed with the plural cone-shaped projections (23b), so as to protect the cone-shaped projections (23b) while being closely attached onto the surface (23c) of the base body (23a). Sealing sheet (9) seals between the cone-shaped projection sheet (23) and the sheet (7) for cone-shaped projection molding while being attached upon the sheet (7) for cone-shaped projection molding.錐狀突起片的包裝體(1)係具備有錐狀突起片(23)、錐狀突起成形用片(7)以及密封片(9)。錐狀突起片(23)係具備有基體(23a)以及形成於基體(23a)的表面(23c)之複數個錐狀突起(23b)。錐狀突起成形用片(7)係具有用以形成複數個錐狀突起(23b)且配置有複數個錐狀突起(23b)之複數個錐狀凹部(33a),並在密著至基體(23a)的表面(23c)之狀態下保護錐狀突起(23b)。密封片(9)係固定於錐狀突起成形用片(7),藉此在與錐狀突起成形用片(7)之間密封錐狀突起片(23)。1‧‧‧錐狀突起片的包裝體3‧‧‧具有支撐體的錐狀突起片5‧‧‧包裝構材7‧‧‧錐狀突起成形用片9‧‧‧密封片21‧‧‧支撐體23‧‧‧錐狀突起片23a‧‧‧基體23b‧‧‧錐狀突起23c‧‧‧表面23d‧‧‧第二表面25‧‧‧第一片26‧‧‧第一黏著層27‧‧‧第二片28‧‧‧第一接著層31‧‧‧收容部35‧‧‧段差面37‧‧‧平坦面41‧‧‧表面樹脂層42‧‧‧第二黏著層43‧‧‧金屬層44‧‧‧第二接著層
