The present invention provides a method of making a laminated, gathered, elastic web. The terminal 57-1 faces the common electrode 19 with an electric insulating layer 61 being on the piezoelectric element 13 side and the first liquid stopper 69-1 being in the gap between the common electrode 19 and the terminal 57-1. In the link mechanism, a sliding speed of the pin sliding in the cam groove is reduced when the pin enters into the bent portion in the cam groove, as compared with the sliding speed before the pin enters into the bent portion.
