Abstract
To obtain, in an on-board control device, a shield effect against noise radiated from an electronic component. The present invention includes: an electronic component 103; a metal housing 101 which covers at least a part of the electronic component 103; a metal portion 105 which is provided so that the electronic component 103 is disposed between the metal portion 105 and the metal housing 101; and a shield structure which shields radiation noise from the electronic component 103 by electrostatic capacitive coupling formed between the metal portion 105 and the metal housing 101.

An electronic control device comprising:
- an electronic component;
- a metal housing which covers at least a part of the electronic component;
- a metal portion which is provided so that the electronic component is disposed between the metal portion and the metal housing;
- a shield structure which shields radiation noise from the electronic component by electrostatic capacitive coupling formed between the metal portion and the metal housing, wherein the metal portion is provided inside a substrate having the electronic component mounted thereon;
- and
- a contact portion between the substrate and the metal housing, the contact portion being sandwiched therebetween and contacting both the substrate and the metal housing, the contact portion being covered by resist and preventing electrical connection between the substrate and the metal housing, wherein the contact portion extends only in an outer periphery of the substrate, and extends along an entirety of the outer periphery of the substrate.
An electronic control device comprising:
- a substrate on which a plurality of electronic components are mounted;
- a metal housing having a housing space for housing the plurality of electronic components,
- wherein a mounting portion on which an outer peripheral edge portion of the substrate is mounted is formed on an entire circumference of the metal housing so as to surround an outer periphery of the housing space, and
- the substrate has a metal portion that covers the housing space and is capacitively coupled to the mounting portion of the metal housing;
- and
- a contact portion between the substrate and the metal housing, the contact portion being sandwiched therebetween and contacting both the substrate and the metal housing, the contact portion being covered by resist and preventing electrical connection between the substrate and the metal housing, wherein the contact portion extends only in an outer periphery of the substrate, and extends along an entirety of the outer periphery of the substrate.
