<p>There is disclosed a die 1 for forming a honeycomb structure comprising a die base 22 having a first plate-like member 23 and a second plate-like member 24, the first plate-like member is provided with groove portions-on the side of a bonding surface 28 between the first plate-like member and the second plate-like member 24, and a depth y (mm) of the groove portions 7 satisfies the following equation (1): y ‰¤ a €¢ t �¢ 1 × E �¢ 1 + t �¢ 2 × E �¢ 2 / t �¢ 1 × t �¢ 2 × E �¢ 1 × E �¢ 2
in which t1 is a thickness (mm) obtained by subtracting the depth (mm) of the groove portions from a thickness (mm) of the first plate-like member, E1 is an apparent volume elasticity (GPa) of the first plate-like member at 25°C in consideration of a state in which back holes are formed, t2 is a thickness (mm) of the second plate-like member, E2 is a volume elasticity (GPa) of the second plate like member at 25°C, and a is a coefficient determined on the basis of conditions during manufacturing.</p> |
