PROBLEM TO BE SOLVED: To provide a sealed cap capable of reducing the amount of resin to be used and also reducing the cost.SOLUTION: The sealed cap includes: a cylindrical member 10 which comprises a cylindrical wall 11 surrounding a peripheral wall 4 of a mouth 3, a female screw 12 corresponding to a male screw 5 in an inner surface of the cylindrical wall 11, and a projection part 13 projecting toward the inner side in the radial direction in an upper part of the cylindrical wall 11; and a lid shaped member 20 which has a top wall 21 closing an opening of the mouth 3 and having a diameter larger than that of an inner edge part of the projection part 13, and a seal cylinder 22 adhering to an inner surface of the peripheral wall 4 in a lower surface of the top wall 21. The lid shaped member 20 has a claw part 24 which extends downward from the lower surface of the top wall 21 and comprises a projecting end part 23 having a diameter larger than that of the inner edge part of the projection part 13. The sealed cap is formed by integrally connecting the cylindrical member 10 and the lid shaped member 20 by connecting the inner edge part of the projection part 13 and the lower end part of the claw part 24 with a thin wall part 30.
