Claim:
A method for water-stopping an electric wire, comprising the steps of: obtaining at least one electric wire having a conductor and a coating material on an outer side of the conductor; clamping a connection terminal having at least one clamping portion on a first end portion of the electric wire; after clamping the connection terminal, feeding a water-stopping agent having a flowability to the at least one clamping portion of the connection terminal and the first end of the at least one electric wire; creating suction in an inner side of the coating material of the at least one electric wire, during or after the feeding of the water-stopping agent, from a second end portion of the at least one electric wire; and reducing a pressure of the inner side of the coating material of the at least one electric wire by the suction step so that the water-stopping agent penetrates between the coating material and the conductor.
