Title:
ELECTRICAL CIRCUIT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/145449
Kind Code:
A1
Abstract:
This electrical circuit device is provided with: a noise generating circuit part where a noise is generated; a case which internally contains the noise generating circuit part and is electrically grounded, while having an opening; a control substrate which is provided with a connector for connecting a wiring line to the outside; a base plate which is arranged between the noise generating circuit part and the control substrate so as to cover the opening of the case; and a high impedance mechanism which has a higher impedance than the base plate with respect to a noise. The base plate comprises a first base plate that supports the control substrate and a second base plate that is separated from the first base plate; and the first base plate and the second base plate are arranged so as to sandwich the high impedance mechanism therebetween.
