A method for manufacturing a honeycomb structure having slits is provided which permits accurate forming of fine slits to cut or grind a targeted cell array alone and which is suitable for application to mass production. The method provides a honeycomb structure having slits and a plurality of arrays of numerous cells aligned in parallel. The slits communicate with an external space and formed along the arrays. The slits are formed by protruding a slit forming member 4-toward the molded article during the extrusion step.

Un método para fabricar una estructura del panal que tiene rajas se proporciona que permita que la formación exacta de rajas finas corte o muela un arsenal de célula apuntado solo y que sea conveniente para el uso a la producción en masa. El método proporciona una estructura del panal que tiene rajas y una pluralidad de órdenes de células numerosas alineadas en paralelo. Las rajas se comunican con un espacio externo y formado a lo largo de los órdenes. Las rajas son formadas resaltando una raja que forma a miembro 4-hacia el artículo moldeado durante el paso de la protuberancia.
