PURPOSE:To make full use of abrasive grains as well as to improve durability in an abrasive belt ever so better, by applying and firmly attaching these abrasive grains to the whole surface of a belt base material where low hardness mineral particles are patterned and tightly attached thereto. CONSTITUTION:First, each low hardness mineral particle 3 being almost identical grain size with each abrasive grain 2 and 2-7 in Mohs' hardness is tightly attached to the surface of a belt base material 1 of a woven fabric or paper at a pitch interval of within 20mm upon patterning round, angular, slanting strope figures in advance. Then, after a bonding agent 4 is applied to the whole surface of this belt base material 1, the abrasive grains 2 are applied thereto uniformly and densely by means of an electrostatic spray painting process, and furthermore the bonding agent 4 for upper coating is applied, making each particle coherent so rigidly, thus such an abrasive belt as capable of utilizing these abrasive grains 2 effectively is produced. That is to say, after each abrasive grain is worn down due to abrasive action, the low hardness mineral particle 3 appears on the surface but this particle 3 is properly crushed down in contact with a work, and since its abrasion is larger than that of the abrasive grain 2, it will not hinder the abrasive action of the next abrasive grain 2.
