Abstract
An extrusion device comprises a die provided with feed passageways and grid-shaped extrusion slots of which width is made larger in the outer peripheral portion compared with those of the central portion of the die. By the above extrusion device, a honeycomb structure having a thicker walled outer peripheral portion can be obtained without any distortion.
