PROBLEM TO BE SOLVED: To prevent adhesion of fine powder by adding a specified wt.% of surfactant, satisfying specified grain size distribution conditions of detergent composition and setting the surface resistance of a weighing unit at a specifiedΩor less. SOLUTION: A surfactant is contained preferably by 27-45 wt.% and the grain size distribution of a high density granular detergent composition is such that the particles having grain size of 180-500μm occupy 85 wt.% or more or the particles having grain size of 180-500μm occupy less than 50 wt.% and the weight ratio of the particles having grain size less than 180μm to the particles having grain size of 500μm or above is preferably 1.5 or above. Surface resistivity of a weighing unit based on ASTM:D257 is preferably 1×109Ωor less. The weighing unit is preferably shaped into a spoon having a scraping part and a grasping part and the material thereof includes plastics, e.g. polypropylene, metals, e.g. aluminum, and papers.
