A portable repetitive transcranial magnetic stimulation (rTMS) apparatus is provided. The rTMS apparatus includes an upper fastening component, a lower fastening component, a driving circuit and an inductor which is electrically connected to the driving circuit and used as a stimulator. The inductor is formed of a core and a coil. The core has a groove. The coil includes an upper part and a lower part. The upper part of the coil is configured to be distal to the core and pass through an upper side, a left side or a right side of the core. The lower part of the coil is configured to pass through the groove.一種可攜式重複透顱磁刺激儀器，其包含一驅動電路以及一電感器。該電感器電性連接至該驅動電路，用以作為一探頭。電感器由一磁芯及一線圈所構成。該磁芯具有一凹槽。該線圈包含一上部及一下部。該線圈之該上部被設置成遠離該磁芯且通過該磁芯之一上方、一左方或一右方。該線圈之該下部被設置成通過該磁芯之該凹槽。
