Disclosed is an end plate for a fuel cell including an anti-bending plate, in which an anti-bending plate is assembled with an insert having a sandwich structure and the insert is injection molded, thereby easily preventing the insert from being bent due to an injection molding pressure. In the disclosed end plate, a sandwich insert including two or more stacked plates each having a specific shape is manufactured, and an anti-bending plate is coupled to the sandwich insert and then is injection molded, thereby easily preventing the sandwich insert from being bent due to a resin pressure in the injection molding process, contrary to a conventional integral metal insert.
