[Problems] To provide detergent granules capable of suppressing paste formability and having low exothermic property; a process for producing the detergent granules; and a high-bulk density detergent composition containing the detergent granules. [Solving Means] Detergent granules containing a sodium linear alkylbenzenesulfonate (LAS-Na), sodium sulfate undetected by X-ray diffraction method and sodium sulfate detected by X-ray diffraction method, wherein a molar ratio of [sodium sulfate undetected by X-ray diffraction method]/[LAS-Na] is from 0.1 to 1.0, and a molar ratio of [sodium sulfate detected by X-ray diffraction method]/[chemically quantified sodium sulfate] is from 0.5 to 0.9; a process for producing detergent granules, including the step of dry-neutralizing a mixture of a liquid acid precursor of a sodium linear alkylbenzenesulfonate (LAS-S) and sulfuric acid with a water-soluble solid alkali inorganic substance in a mixture containing powdery anhydrous sodium sulfate, wherein sulfuric acid is present in a ratio of 0.1 to 1.0 mol to one mol of the LAS-S, and the powdery anhydrous sodium sulfate is present in a ratio of from 0.5 to 0.9 mol to one mol of a total of the powdery anhydrous sodium sulfate and sulfuric acid; and a high-bulk density detergent composition having a bulk density of 500 g/L or more, containing the detergent granules as defined above, or detergent granules obtainable by the process as defined above.
