To shield against electromagnetic waves with the use of a simple structure.SOLUTION: An electronic unit comprises: a substrate on which an electronic component is mounted; a first cover covering one surface of the substrate; a second cover covering the other surface of the substrate; and a case which is fitted to the second cover while covering the substrate and the first cover. The first cover has: an upper plate part facing the substrate; a lateral plate part protruding from a peripheral edge of the upper plate part; and a contact part provided at an end of the lateral plate part. The second cover has a crest part. The contact part is bent toward either the inside or the outside so that the first cover and the second cover are brought into conduction with each other when the contact part of the first cover comes into contact with the crest part of the second cover.SELECTED DRAWING: Figure 4 【課題】簡易な構造で電磁波を遮蔽すること。【解決手段】本開示に係る電子ユニットは、電子部品を実装した基板と、前記基板の一方の面を覆う第１カバーと、前記基板の他方の面を覆う第２カバーと、前記基板及び前記第１カバーを覆いつつ、前記第２カバーに取り付けられるケースと、を備える。前記第１カバーは、前記基板に対向する上板部と、前記上板部の周縁から突出する側板部と、前記側板部の端部に設けられた接触部とを有する。前記第２カバーは、山部を有する。前記接触部は、内側又は外側の片側に向かって湾曲しており、前記第１カバーの前記接触部と前記第２カバーの前記山部とが接触することによって、前記第１カバーと前記第２カバーとが導通する。【選択図】図４
