PROBLEM TO BE SOLVED: To provide a double cup on which information expressed by characters, pattern, etc., is printed on a part difficult to see, such as a cylinder, and the information is revealed when the cylinder is cut away. SOLUTION: The double cup (1) has a paper cup body (10) which includes a body (11), a bottom (12), has a rim (13) formed by curling the outer peripheral edge of an opening outward. The outer peripheral edge of the bottom (12) is bent downward to form a bent portion (14), and the lower end of the body (11) is folded inward to hold the bent portion (14) inside the lower end, which is then heated and pressure bonded to be connected to the bottom (12) to form the cup body (10). The double cup also has the cylinder (20) which is wounded around the outer periphery of the body (11) of the cup body (10) and is pasted at a pasting part. A cutaway portion (21) is formed on the cylinder (20), and a displaying portion (22) is provided on the cutaway portion (21) of the cylinder (20), and/or on the body (11) of the cup body (10) that overlaps the cutaway portion (21) of the cylinder (20).
