Abstract: A device includes a circuit board, a power conversion module disposed to face the circuit board, a bus bar connected to the power conversion module, and a shielding portion that shields an electromagnetic wave. The bus bar extends through a side edge of the circuit board from one side to an opposite side of the circuit board along a thickness direction of the circuit board. The shielding portion is disposed between the bus bar and the side edge of the circuit board, extends from the one side to the opposite side along the thickness direction of the circuit board, and extends to both sides of the bus bar along the side edge of the circuit board.

Abstract: Provided is an electronic control device that is easily assembled and with which it is possible to reduce the effects of vibration and external force applied from a connector. Electronic components are installed on a substrate. A base covers a surface of the substrate. A cover covers a surface of the substrate. A first connector, which is installed on the surface, connects to a connector fixed to an on-board transmission. A second connector, which is installed on the surface, connects to a connector of a harness. First vibration-suppressing parts, which are provided to the inside surface of the base facing the end surface of the first connector on the surface side, suppress the vibration of the first connector.

Abstract: The purpose of the present invention is to provide a control unit whereby the quantity of a seal material to be used can be reduced, while ensuring waterproof performance. This electronic control device is provided with: a housing, wherein a plurality of members are bonded, and a peripheral end portion thereof is configured from a plurality of sides; a circuit board housed in the housing; and seal structures that are disposed along the sides at the peripheral end portion. A seal material is provided to the seal structures such that the members are connected to each other. The seal structures disposed on one side of the peripheral end portion are configured such that each of seal cross sectional areas at end portions of the side is smaller than a seal cross sectional area at a center portion of the side.
