摘要：The purpose of the present invention is to provide a metal mold to manufacture a corrugated plate for a fuel cell which prevents a stress concentration on a bent part, and has a wide contact area; and a method to manufacture the corrugated plate using the same. In order to achieve this purpose, the metal mold to manufacture the corrugated plate for the fuel cell comprises: a plate which is plate-shaped and made of a metal material; a contact surface which protrudes upwards from the metal plate; dies which form a groove which is concave downwards to as much as a protrusion on the contact surface to manufacture the metal plate including a slit of an inclined surface which connects the metal plate and the contact surface; and a punch arranged on an upper part of the dies, forming a projection protruding downwards as much as a contact surface protrudes from the plate wherein the inclined surface relatively has a thinner thickness than the plate and the contact surface.
