Abstract: A carbonaceous refractory which generates little decomposition gas having a foreign odor, is excellent in spalling resistance and has kneadability and moldability equivalent or superior to those of a phenolic resin; and a process for the production thereof. The above refractory is characterized in that starch sugar and/or reducing starch sugar is used as the binder instead of the phenolic resin used in the prior art. More specifically, the above refractory is produced by using a binder comprising 40 to 80 % by weight of starch sugar and/or reducing starch sugar and 20 to 60 % by weight of water, or a binder comprising 40 to 80 % by weight of starch sugar and/or reducing starch sugar, 1 to 25 % by weight of water, and 5 to 50 % by weight of an alcohol having a boiling point of 80 DEG C or above.
