Abstract: A vacuum-sealing device includes external cylinder part (501B) which includes a distal end face that is brought into airtight contact with an outer face of a container that is a vacuum-sealing target to cover an exhaust hole of the container, and includes body part (501A) provided within external cylinder part (501B) and movable forward and backward along an axial center of external cylinder part (501B). The vacuum-sealing device further includes driver (503) that moves external cylinder part (501B) and body part (501A) forward and backward in the direction of extension of the axial center of external cylinder part (501B), and heater (504) that heats distal end portion (51) of body part (501A). Exhaust space (58) communicating with the distal end face of external cylinder part (501B) is formed between an outer circumferential face of distal end portion (51) of body part (501A) and an inner circumferential face of external cylinder part (501B).
