摘要
Contamination of a washing liquid in a washing tank is suppressed at a downstream side of a path for transferring a film. A washing device includes a roller for transferring a heat-resistant separator from a washing tank to another washing tank. Two rollers contact one surface of the heat-resistant separator, and a remaining roller, between the two rollers, contacts the other surface of the heat-resistant separator. A washing liquid removed from the heat-resistant separator by the remaining roller returns to the washing tank.
