PROBLEM TO BE SOLVED: To provide a method of mounting a conductive ball, the method correctly mounting a conductive ball on an electrode even when the position of an opening of an arrangement mask does not coincide with that of the electrode due to a dimensional error or temporal deterioration of the arrangement mask. SOLUTION: The method of mounting a conductive ball for mounting the conductive ball on the electrode of an object to be mounted through an opening of an arrangement mask employs the following steps: a first step of arranging the arrangement mask above the object; a second step of supplying the conductive ball to the upper surface of the arrangement mask to drop the conductive ball into the opening of the arrangement mask; a third step of relatively separating the arrangement mask from the object until the lower end of the opening of the arrangement mask and the electrode of the object has a predetermined distance; and a fourth step of mounting the conductive ball on the electrode by relatively finely moving the arrangement mask and the object on a horizontal plane.
