Title:
ELECTRONIC CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/276231
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electronic control device that can improve EMC resistance when a case made of resin is used rather than using a case made of metal. This electronic control device comprises a substrate 101, an electronic component 302 arranged on an electronic component mounting surface 101a of the substrate 101, and a case made of resin 100 that stores the substrate 101. The case 100 has an electrically conductive member 102 on the surface facing the electronic component mounting surface 101a of the substrate 101. The substrate 101 has a plurality of electrically conductive surface mount members 301 mounted on the electronic component mounting surface 101a to surround the electronic component 302. The plurality of electrically conductive surface mount members 301 are each arranged separated on the electronic component mounting surface 101a, and form an electrical shield by contacting the electrically conductive member 102.
