1. A method for manufacturing a honeycomb structure that includes partition walls partitioning a plurality of cells, the method comprising:
molding a molded body from a mixture containing silicon carbide particles, an organic component, and a dispersion medium;
removing the organic component included in the molded body to obtain a porous honeycomb body; and
impregnating an inner portion of the partition walls of the porous honeycomb body with metal silicon,
wherein in a state in which the porous honeycomb body is placed on a support inside a container containing solid metal silicon, said impregnating is performed by heating the inside of the container to a temperature higher than or equal to a melting point of the metal silicon so that the porous honeycomb body is impregnated with molten metal silicon through the support that is porous, and
further comprising heating the porous honeycomb body at a temperature higher than or equal to 1800° C. between said removing and said impregnating.
