PROBLEM TO BE SOLVED: To provide a method for firmly fixing fine particles of diamond onto an electroconductive tool and a diamond tool capable of being used in a wet processing in the method for fixing the fine particles of diamond onto the electroconductive tool and the diamond tool produced by using this fixing method. SOLUTION: This method for fixing fine particles of diamond is to charge a voltage on a suspension obtained by suspending fine particles 39 of diamond in water and an electroconductive tool 31 and fix the fine particles of diamond to the electroconductive tool by electrophoresis. In this case, sodium hexametaphosphate 41 or sodium pyrophosphate which is a dispersant for the fine particles of diamond is mixed together with polyvinylpyrrolidone 43 and a silane coupling agent 45 into the suspension. |
