PROBLEM TO BE SOLVED: To provide an electronic control device capable of suppressing the deterioration of seal performance on a joint portion between a seal groove and a connector seal surface.SOLUTION: Such a seal groove 20 having U-shaped cross section that a protrusion part which is protruded on a lower surface of an outer circumferential part of a cover member 3 is squeezed into sealant filled to an inner part and, thereby, secures a seal length is provided on an upper surface besides a front edge wall 7a of an outer circumferential wall 7 of a base member 2, both edge parts (extension surface 15a) of a first connector seal surface 15 are extended and formed along the width direction of the connector 5, at the same time, joint parts 22 are provided on both edge parts of a groove part 21 of the seal groove, the joint parts are connected from a vertical direction with respect to the extension surface and, at the same time, respective bottom surfaces 22a are formed so as to be tapered upward and are continuously connected to an extension surface via the top edge 22b.

    【課題】シール溝とコネクタシール面との繋ぎ目箇所のシール性能の低下を抑制することができる電子制御装置を提供する。【解決手段】ベース部材2の外周壁7の前端壁7a以外の上面に、内部に充填されたシール剤をカバー部材3の外周部下面に突設された突起部が押し込んでシール長を確保する横断面U字形状のシール溝20を設け、第1コネクタシール面15の両端部(延長面15a)を、コネクタ5の幅方向に沿って延長形成すると共に、シール溝の溝部21の両端部に繋ぎ部22を設け、該繋ぎ部を、前記延長面に対して直交方向から連結すると共に、各底面22aを上方に向かってテーパ状に形成してこの先端縁22bを介して延長面に連続的に連結した。【選択図】図5
