To provide an electric circuit arrangement which achieves improvement of an electromagnetic shield performance to improve noise resistance.SOLUTION: An electric circuit arrangement includes: a conductive first case 100 forming a storage space of an electric circuit; a conductive second case 200 being connected to the first case 100 and forming the storage space: and a seal material 300 which contacts with the first case 100 and the second case 200. The first case 100 side in a connection part between the first case 100 and the second case 200 has a first surface and a first protruding surface protruding to the second case side farther than the first surface. In the connection part, the second case 200 side has a second surface which contacts with the first protruding surface and a second protruding surface protruding to the first case 100 side farther than the second surface and facing the first surface. The second protruding surface is formed so as to provide a first space 111 and a second space 112 with the first surface. The seal material 300 is disposed in the first space and the second space.SELECTED DRAWING: Figure 3(d)
【課題】電磁シールド性を向上させ耐ノイズを向上する電気回路装置を提供する。【解決手段】電気回路装置は、電気回路の収納空間を形成する導電性の第1ケース100と、第1ケース100と接続し、かつ、収納空間を形成する導電性の第2ケース200と、第1ケース100と第2ケース200と接触するシール材300と、を備える。第1ケース100と第2ケース200の接続部において当該第1ケース100側は、第1面と、当該第1面よりも当該第2ケース側に突出する第1突出面と、を有する。前記接続部において、第2ケース200側は、前記第1突出面と接触する第2面と、当該第2面よりも第1ケース100側に突出し、かつ、前記第1面と対向する第2突出面とを有する。第2突出面は、前記第1面との間に第1空間111と第2空間112を設けるように形成され、シール材300は、第1空間と第2空間に配置される。【選択図】図3(d)
