ELECTRONIC APPARATUS

摘要

A case (3) has a penetrating hole (7), which is provided with a breathable film (15). A protective structure comprises a protective ring (9) and a protective cap (17), and is provided outside the case (3) so as to cover the breathable film (15). A gap (41) between the protective ring (9) and the protective cap (17) is an opening connecting the inside and outside of the protective structure. In a cross-sectional view, an outside upper edge of the opening (i.e. point B) is positioned on or inside a straight line connecting an outer edge of the breathable film (15) (i.e. point C) and an inside lower edge of the opening (i. e. point A). The breathable film can be protected from an intentional load applied thereto.
