It is provided an electronic control device including a resin molded body, a metal body, and an electronic component, wherein the resin molded body and a main surface of the metal body are bonded, and at least a part of a side surface continuous to the main surface of the metal body is in contact with a side contact portion provided in the resin molded body.

Electronic control device and method for manufacturing electronic control device

An antenna base, a control circuit section, and a high-frequency circuit section are enclosed in an inner space defined by a housing and a radome. Inside this inner space, the control circuit section and the high-frequency circuit section are surrounded by the antenna base and the housing. A circuit GND common to the control circuit section and the high-frequency circuit section is electrically connected to the antenna base and the housing, and it is connected to a body GND through only capacitive impedance.

Vehicle-mounted radio wave radar

A high-frequency communication apparatus has a case containing a transmitter-receiver including circuit elements. A functional structure capable of confining radiation energy radiated by unnecessary radio wave source to prevent the radiation energy from interfering with the operations of the transmitter-receiver is formed on at least one of the walls of the case by forming a plurality of projections in regular arrangement by press working. The circuit elements of the transmitter-receiver are packed in the case to suppress the undesired electromagnetic coupling of internal and external electromagnetic waves with the circuit elements of the transmitter-receiver.
