A method of manufacturing a cordierite porous body of the present invention is a method of manufacturing the cordierite porous body using a cordierite forming material including an Al source, an Si source, and an Mg source and forming cordierite by firing, characterized in that an inorganic micro balloon containing SiO2 and Al2O3 is used as a part or all of the Al source and the Si source, so that a high-open-porosity cordierite porous body having an extremely low possibility of generating defects causing leakage of a fluid, such as cuts can be manufactured.
