A plurality of flat tablets are held in containing holes (211) by pinching the circumferential edge of the flat tablet (t) at the lowermost position at the lower end of the containing hole, and then pinching state of the tablet (t) at the lowermost position is released thus dropping the plurality of flat tablets (t) under a flat state into a capsule body (m) arranged below. The capsule body can be surely filled with a predetermined number of flat tablets under a flat state by preventing occurrence of flat tablets under a standing state effectively.
