FUEL CELL SEPARATOR MANUFACTURING METHOD AND FUEL CELL SEPARATOR

Provided is a manufacturing method of a fuel cell separator and a fuel cell separator that can prevent a reduction of a sealing property. The manufacturing method of the fuel cell separator includes an overlaying step of overlaying a first metal separator (21) and a second metal separator (22) together, the first metal separator (21) and the second metal separator (22) each including a flat portion (30) and a bead portion (31) protruding from the flat portion (30), a welding step of welding along the bead portion (31) overlaid flat portions (30), and in the welding step, a weld meeting point (Z) where welded portions meet is formed at an area which is away from the bead portion (31) and/or which is to be a high stiffness part (U) with a high stiffness on a welding path.
