Abstract
A honeycomb structure-forming diehas a die substrateincluding a first plate-shaped memberhaving back holesfor introducing a raw forming material and a second plate-shaped memberhaving slitsfor forming the material into a lattice shape. The first plate-shaped memberhas columnar portionswhere at least a part is zoned by a slit-shaped groove portioncorresponding with a shape of the sliton a bonding face sidewhere the first plate-shaped memberis bonded with the second plate-shaped member. In the columnar portions, the ratio (L/T) of the height L of the columnar portionsto the minimum width T in an end face on the bonding face sideis within 1/3 to 3.5. Thus constituted die realizes high formability, and two plate-shaped members constituting the die substrate are hardly peeled from each other.
