Abstract: An object of the present invention is to provide an electronic control device that can be improved in EMC resistance when a resin case is used without using a metal case. An electronic control device of the present invention includes: a substrate 101; an electronic component 302 disposed on an electronic component mounting surface 101a of the substrate 101; and a resin case 100 that houses the substrate 101. The case 100 includes a conductive member 102 on a surface facing the electronic component mounting surface 101a of the substrate 101. The substrate 101 includes a plurality of conductive surface-mounted members 301 mounted on the electronic component mounting surface 101a to surround the electronic component 302. The plurality of conductive surface-mounted members 301 are arranged to be separated from each other on the electronic component mounting surface 101a and form electrical shielding by coming into contact with the conductive member 102.
