PROBLEM TO BE SOLVED: To solve the problem that in a shape of a head set used for non-invasive brain electric stimulation, an electrode position cannot be changed, and in a simple head set, in particular, the scope of the head on which an electrode is press-fitted is limited.SOLUTION: An attachable/detachable movable type electrode is provided, which slides on a head set body 1. The electrode is a sponge held by a sponge holder 2 for the attachable/detachable electrode, which slides on the head set body 1, for example. Thanks to the sponge holder 2 for the electrode that slides on the body 1, an installation range for the electrode press-fitted to the head is enlarged, thereby making it easy to change the position of the electrode.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】非侵襲的脳電気刺激に用いるヘッドセットの形状は、電極の位置が変更不能であり、特に簡易なものでは、電極を圧着する頭部の範囲が限定されてしまう。【解決手段】ヘッドセット本体1上をスライドする着脱可能な可動式の電極を設ける。電極は例えば本体1上をスライドする着脱可能な電極用スポンジ保持器2に保持されたスポンジである。本体1上をスライドする電極用スポンジ保持器2のおかげで、頭部に圧着する電極の設置範囲が広がり、位置変更しやすくなる。【選択図】図1
