There are provided a honeycomb structure and a method of manufacturing the structure, capable of preventing or reducing generation of CO<SUB>2 </SUB>or harmful gas during firing to thereby prevent or inhibit pollution and global warming, and capable of obtaining a honeycomb structure having few defects such as cracks and maintaining high strength and low thermal expansion. In a method of manufacturing a honeycomb structure, in which a forming material containing a cordierite forming material and an organic binder is kneaded and formed to prepare a honeycomb-shaped formed article (honeycomb formed article), and the prepared honeycomb formed article is fired to obtain a honeycomb-shaped structure (honeycomb structure) mainly composed of cordierite: the forming material containing a layered clay mineral whose layer charge (X) is 0.2<X<=2 in addition to the cordierite forming material and the organic binder is used; a total amount of at least one element selected from a group consisting of sodium, potassium, and calcium contained in the layered clay mineral is set to 0.5% by mass or less in terms of oxide with respect to a total with the cordierite forming material; and a content ratio of the organic binder is set to 5 parts by mass or less with respect to 100 parts by mass in total of the cordierite forming material and the layered clay mineral.
