A die for extrusion molding of a honeycomb which comprises a structure provided with a groovy slit (2) formed by cell blocks (3) on a front face thereof, and additionally provided with a puddle inlet, on a back face thereof, communicatively connected with the slit (2), wherein each cell block (3) has a soft film (16) on a hard film (14) formed on outermost surfaces of the slit (2) and puddle inlet fabricated in a cell-block body (10). According to the die for extrusion molding of a honeycomb, a dimensional error of the die is possible to be eliminated, a stable force of extrusion friction is possible to be maintained, both extrusion moldability and abrasion resistance are possible to be excellent, and additionally an adjustment of the die at the time of extrusion molding can be performed easily.
