浸入を完全に阻止できる構造に構成されている。Further, the electromagnetic wave shield structure 2 is provided with a noise filter 4 and a shield air-conditioning port 5 separately from the electromagnetic wave shield structure 1. The noise filter 4 is for shielding electromagnetic waves that try to enter through electric cables such as electric power lines and signal lines that are drawn into the electromagnetic wave shield structure 2, and the shield air conditioning opening 5 is provided inside the electromagnetic wave shield structure 2. It takes in outside air and has a structure that can completely block the entry of electromagnetic waves.
