To provide an electrode unit that increases the electroporation effect while suppressing the occurrence of short circuit failure due to migration.SOLUTION: An electrode unit 20 that is brought into contact with the skin includes: a first electrode 22 and a second electrode 24 in which voltage is applied therebetween; and an insulating substrate 23 which is placed between the first electrode 22 and the second electrode 24. The first electrode 22, the second electrode 24 and the substrate 23 are layered and stacked together. A first body 22a being the body of the first electrode 22 and a second body 24a being the body of the second electrode 24 are smaller than a substrate body 23a being the body of the substrate 23 in the stacking direction view. The first body 22a is arranged on the side that comes into contact with the skin with respect to the second body 24a and has a notch 22f as a first penetration part that penetrates along the stacking direction.SELECTED DRAWING: Figure 6 【課題】マイグレーションによるショート不良の発生を抑えつつエレクトロポレーション効果を高める電極ユニットを提供する。【解決手段】皮膚に接触させる電極ユニット２０であって、互いの間で電圧が印加される第１電極２２及び第２電極２４と、第１電極２２と第２電極２４との間に配置される絶縁性の基材２３と、を備え、第１電極２２、第２電極２４及び基材２３は、各々層状で、かつ、互いに積層され、第１電極２２の本体である第１本体２２ａ、及び、第２電極２４の本体である第２本体２４ａは、積層方向視で、基材２３の本体である基材本体２３ａよりも各々小さく、第１本体２２ａは、第２本体２４ａよりも皮膚に接触する側に配置され、かつ、積層方向に沿って貫通する第１貫通部としての切り欠き部２２ｆを有する。【選択図】図６
