PROBLEM TO BE SOLVED: To provide a grain supply device which can be used in liquid. SOLUTION: An abrasive grain supply device 10 includes: an abrasive grain transferring pipe 60; an abrasive grain extruding pipe 100; an abrasive grain holding recess 190; and an abrasive grain extruding mechanism 80 composed of an extruding pin 110 and a lever. One abrasive grain 170 held at an abrasive grain holding recess 190 is just extruded with the extruding pin 110 moved by the lever. Accordingly, the abrasive grain supply device 10 is used even in electrodeposition liquid without trouble, so that it can be used in the electrodeposition liquid. COPYRIGHT: (C)2011,JPO&INPIT
