PROBLEM TO BE SOLVED: To provide a granular detergent composition compatible with the suppressions both of classification and solidification. SOLUTION: The granular detergent composition contains at least two kinds of particles in which the total contents excluding the particles of the largest content is 3-50 mass%, and a tensile rupture stress is 3,000-60,000 Pa. The composition is obtained by mixing particles having Z1 of an inclination in Rosin- Rammler plot with another type of particles having a composition and/or production method different from the composition and/or the production method of those particles and having Z2 of an inclination in Rosin-Rammler plot. In the composition, a mode in which the ratio of Z1/Z2 is 1/2 to 2/1, and a mode in which the composition is obtained by mixing particles existing in a region surrounded with straight lines of y=0.5417x+0.172, y=0.7643x-0.815, x=1.50 and x=2.05 wherein x is a true density of the group of the particles, and y is a bulk density of the group of the particles, are preferable.
