A method for manufacturing a honeycomb structure includes a tubular circumferential wall and partition walls forming a honeycomb-shaped cross-section and defining a plurality of cells extending inside the circumferential wall in the axial direction of the circumferential wall. The method includes a molding process, a degreasing process, and an impregnation process. The molding process molds a mixture including ceramic particles, an organic binder, and a dispersion medium to obtain a molded body. The degreasing process removes the organic binder included in the molded body to obtain a degreased body. The impregnation process impregnates the inside of the circumferential wall and the partition walls of the degreased body with metal silicon. The impregnation process is performed under an inert gas atmosphere or a vacuum at a temperature between 1400° C. and 1900° C.
