摘要： A manufacturing method for manufacturing a fuel cell includes a laser application step and a bonding step. In the laser application step, a laser beam is applied to a carbon film of a separator including a metal plate and the carbon film covering a surface of the metal plate such that the metal plate is exposed by removing the carbon film within an application range of the laser beam. In the bonding step, the separator is bonded to a resin member within a range including at least part of a range where the metal plate is exposed.
