Abstract
There is provided a flexible circuit board capable of preventing corrosion and elution of a conductor layer constituting a current collector even under high-temperature and high-voltage working conditions while achieving sufficient electric connection with an MEA. A flexible circuit board having a current collector of a fuel cell provided thereon includes an insulating flexible base material, a plurality of openingsthat supply fuel or air, the openingsbeing provided in a specified region so as to penetrate through the flexible base materialin a thickness direction, a plating filmthat constitutes the current collector, the plating filmbeing formed on front and back surfaces of the flexible base materialin the specified region and on inner walls of the openings, a surface treatment filmformed on the plating filmand having corrosion resistance higher than that of the plating film.
