A ball arranging method for a ball bearing includes in this order a ball inserting step of inserting a plurality of balls into one region along a circumferential direction of an annular space formed between an inner ring and an outer ring, a flow stopping step of placing a flow stopping jig on a circumferentially outer side of the one region in the annular space so as to hold the inserted balls within the one region, and a ball separating step of sequentially inserting, in an axial direction, tip ends of a plurality of working arrows protruding correspondingly to a number of the balls between the balls while the flow stopping jig is removed from the annular space from a state of being placed in the annular space, so as to arrange the balls at equal intervals in the circumferential direction.
