PROBLEM TO BE SOLVED: To provide a filter aid supply device adapted to a filter using a filter aid comprising porous fine particles and capable of supplying the filter aid while cutting the same even if the filter aid is solidified by moisture absorption. SOLUTION: The bottom wall of a filter aid tank storing the filter aid comprising porous fine particles is constituted of a pair of inclined bottom walls forming an almost V-shaped cross section to form a falling hole by cutting the lower end part of one of a pair of the inclined bottom walls. A shutter and cutter blade for opening and closing the falling hole is supported along the inner surface of the inclined bottom wall, which has the falling hole, among a pair of the inclined bottom walls of the filter aid tank in a movable manner and a push-out blade for discharging the filter aid in the tank from the falling hole is supported along the inner surface of the other inclined bottom wall in a movable manner, and the shutter and cutter blade and the push-out blade are independently driven reciprocally.
