1. A bonding method for bonding two continuous sheet-shaped members and a cylindrical body interposed between the two continuous sheet-shaped members, comprising:
an arrangement step for locating the cylindrical body between the two continuous sheet-shaped members;
a cylindrical body bonding step for bonding the cylindrical body to the two continuous sheet-shaped members by applying an ultrasonic wave to an outer surface of a first one of the continuous sheet-shaped members using a horn part, and applying heat to an outer surface of a second one of the continuous sheet-shaped members using an anvil part, in a state where the cylindrical body is interposed between the two continuous sheet-shaped members; and
a shoulder part bonding step for directly bonding the two continuous sheet-shaped members together at a location between adjacent cylindrical bodies by a pair of heaters on opposite sides of the two continuous sheet-shaped members between the pair of heaters, in a state where the cylindrical body is interposed between the two continuous sheet-shaped members.
