To provide an end structure or an end connecting method of a pipe member for connecting a new pipe end to the end part of an upstream existing pipe member, dispensing with an interception bag for intercepting an upstream pipe member to save the work space at the end part of the upstream pipe member, preventing the end part from entering from the ground boundary toward the downstream, and simplifying the work in a field in connecting the new pipe on the downstream side.

An airtight film 11 for intercepting the end part is provided in the end part of the pipe member 10 on the upstream side, and the airtight film 11 can be linearly cut and removed through a removal hole 41A formed in a connecting part 41 after the new pipe end part 40 is connected to the pipe member 10.
