ELECTRONIC DEVICE, INFORMATION PROCESSOR, AND ELECTROMAGNETIC RADIATION SUPPRESSING MEMBER

摘要

A CPU (3) has an integrated circuit element (32) that is mounted on a CPU circuit board (31), a heat- diffusing board (33A) for diffusing heat that is arranged on the CPU circuit board (31) to cover the integrated circuit element (32), and an electromagnetic radiation suppressor (5). The electromagnetic radiation suppressor (5) has an electromagnetic radiation suppressing member (5A). The electromagnetic radiation suppressing member (5A) abuts on the heat- diffusing board (33A) as well as on ground patterns (G) formed on a mother board M to electrically connect them for suppressing radiation of electromagnetic waves generated from the CPU (3). The electromagnetic radiation suppressing member (5A) includes a frame (51) that has a substantially rectangular shape in plan view and encloses the sides of the heat-diffusing board (33A), and circuit board abutments (52) projecting outward from the frame (51).
