Abstract: An ultrasonic sealing anvil is provided which is capable of applying an optimal pressure to an overlap part in the absence of misalignment between the overlap part and the anvil, and preventing application of an excessive pressure in the occurrence of misalignment. An ultrasonic sealing anvil is configured to seal a tubular material having an overlap part extending in one direction, in a sealing direction crossing the overlap part. The anvil is provided with a step that can be abutted with the overlap part R, and a pair of grooves arranged sandwiching the step in the sealing direction.
