Document Type and Number:
WIPO Patent Application WO/2024/047809
Kind Code:
A1
Abstract:
The purpose of the present invention is to comprehensively perform a noise countermeasure even for electronic components mounted to any of a plurality of circuit boards provided in an electronic control device. This electronic control device 100 comprises a first circuit board 4 and a second circuit board 5 in which respective mounting surfaces 4a, 5a for electronic components 8 are disposed facing each other with a gap therebetween. Furthermore, this electronic control device 100 of a first embodiment comprises a shielding member 9 that is disposed in the gap between the first circuit board 4 and the second circuit board 5 and shields noise, and conductive members 10a, 10b that connect the first circuit board 4 and the second circuit board 5 to the shielding member 9. The shielding member 9 is a frame body that surrounds the entire circumference around the electronic components 8 mounted on each of the first circuit board 4 and the second circuit board 5 and forms a closed path that has a width corresponding to the gap.
