Abstract: A vacuum-sealing device includes: a first roll; a second roll that contacts the first roll; a first holding member having a first space in which the first roll is held and which has an axis coincident with an axis of the first roll; and a second holding member having a second space in which the second roll is held and which has an axis coincident with an axis of the second roll. The first holding member has an inner circumferential surface that faces the outer circumferential surface of the first roll, and rotation of the first roll and the second roll in correspondence with each other causes a sheet material to pass.
