Claims

[Scope of utility model registration request]

A grounding structure for electronic components, in which a printed wiring board on which electronic components are mounted is housed in a metal case with a gap provided between it and the bottom wall, and the grounding part of the electronic component is grounded to the metal case. In this step, a portion of the bottom wall of the metal case facing the ground portion of the electronic component is bulged out so as to come into contact with the printed wiring board, and the bulged portion and the ground portion are tightened with the printed wiring board in between. A grounding structure for an electronic component, characterized in that the grounding part is fixed by a member, and the grounding part is directly electrically connected to a metal case by the fastening member.
