PROBLEM TO BE SOLVED: To provide a guide roll device that can transfer film stably without lowering the quality and yield, a supply method of electricity to the roll guide device and a removal method of electricity from film. SOLUTION: The guide roll device 1 that transfers a tape-shaped film is equipped with a roll section 2 that rotates around a central shaft and comes into contact with the tape-shaped film, a shaft section 3 that is connected to the roll section 2 and rotates together with the roll section 2 and a bearing section 6 supporting the shaft section 3, and a conductive liquid tank 5 in which by sealing a conductive liquid is sealed air tightly around the shaft section 3 in the bearing section 6 and the bearing section 6 and the shaft section 3 are connected electrically through the conductive liquid tank 5. The supply of electricity to the guide roll device 1 is made by supplying a specified electric potential to the guide roll device through the conductive liquid tank 5. The removal of electricity from the conductive liquid tank 5 is made by release of a charge from the film to the outside.
