PROBLEM TO BE SOLVED: To provide a particle group for carrying a surfactant, hardly causing reduction of appearance, solubility or the like, making a coating better, and having excellent preservation stability; to provide a method for producing the particle group; and to provide a method for producing a detergent particle group obtained by using the particle group for carrying the surfactant. SOLUTION: The particle group for carrying the surfactant, containing a water-soluble polymer and water-soluble salts includes at least a part of particles (bonded particles) in an aspect in which two or more particles for carrying the surfactant are bonded, and one or more particles in the bonded particles having ≤1/2 diameters of the largest particles (nuclear particles) in the particles constituting the bonded particles are attached to the nuclear particles. The particle group for carrying the surfactant on a sieve including the particles having an average particle diameter obtained by a method regulated by the standard of JIS Z 8801 has ≤0.83 circular degree (X) represented by the formula: X=(4πA) 1/2 /P [wherein A is a projected area; P is the length of the perimeter of a projected image], and the content of particles having COPYRIGHT: (C)2004,JPO
