A portable electronic apparatus has a water-resistant structure in which a cover covers a surface of an opening formed in a casing of the portable electronic apparatus. The portable electronic apparatus includes a mounting unit that has an outer peripheral surface to which frame-shaped packing that encompasses the opening is attached, and is formed on any one among the casing and the cover; and a groove that is formed on an outer peripheral surface of the mounting unit, and holds the frame-shaped packing therein enabling a surface of the frame-shaped packing to be brought into pressure contact with any one among the casing and the cover to which the mounting is not formed. The mounting unit has a side and a corner, and is of a shape that encompasses the opening, and the groove has a shape at the corner different from that along the side. |
