Abstract

A shielding case includes a case body. The case body and the circuit board enclose a shielded region, and at least part of elements on the circuit board are capped inside the shielding case. The elements located inside the case body include a first component, where the first component has a step surface facing the case body. A reinforcing part is provided in a region on the case body corresponding to the step surface of the first component, where at least partial structure of the reinforcing part is located in a region on the case body facing to the step surface.

First claim
