PROBLEM TO BE SOLVED: To provide a sealing cap having printability and PP properties excellent in metallic luster and having no risk of hurting users' hands, as is often the case with a sealing cap made of aluminum. SOLUTION: A first slit 3a is formed at a lower part of a side wall 2b provided in a suspended state from an edge of a top cover 2a of a metal cap main body 2, and a second slit 3b is formed at an upper part of the side wall 2b, which is in the vicinity of the top cover 2a. A base portion 5 made of resin is formed integrally with the side wall 2b on the inner and outer sides of the lower end of the side wall 2b through the first slit 3a, and a ring portion 4 to be connected with the base portion 5 through a joint portion 6 is formed integrally with the base portion 5. Further, an annular portion 8 made of resin is formed along an outer periphery of a portion where the second slit 3b of the side wall 2b is formed, and a seal portion 9 is formed integraly with the annular portion 8 through the second slit 3b on the lower face of the top cover 2a of the metal cap main body 2. |
