Summary:PURPOSE:To simplify and miniaturize the constitution by reducing the capacity of a storage part in response to a mechanical motion of a magnetism sensitive driving member which is provided in a container and responds by being induced by magnetism given from the outside of the body. CONSTITUTION:A drug containing chamber 7 of a capsule main body 1 is filled in advance with a drug 6, for instance, an antibiotic, etc., for curing a disease. In such a state, this capsule main body 1 is brought to oral dose. When the capsule main body 1 reaches the large intestine in a body cavity, the capsule main body 1 receives magnetic force from a magnet fixed to the belly wall of the part corresponding to the large intestine of a patient, and by this magnetic force, a bag-like member 10 placed in an operating chamber 9 of the capsule main body 1 moves to a cover part 2 side due to a fact that metallic balls 11 are attracted. By following this movement, a piston 5 is pushed, the capacity of the drug containing chamber 7 is varied to the reduction side, and the pressed drug 6 is discharged into the large intestine from a discharge port 8.
