PROBLEM TO BE SOLVED: To provide an electrostatic close contact device, with which bound bubbles become fewer than those developing in the electrostatic close contact device with a conventional technique. SOLUTION: This electrostatic close contacting device is so constituted so to closely contact a sheet 3 extruded from a slot die 2 having at least one electrode 4, which is arranged parallel and near to the surface of a take-up roll 1. In this case, in addition to at least one electrode 4, one more electrode 5 is arranged apart from the surface of the take-up roll 1 so as to apply voltage, which is the same of different one applied to the electrode 4, to the electrode 5 in order to add an electric field more to the electric field developed with the electrode 4. |
