PROBLEM TO BE SOLVED: To implement high waterproof performance in an electronic apparatus with which an article accommodation chamber is formed inside of a casing 1, a lid body 2 covering the accommodation chamber is provided and a waterproof packing 4 is attached to an inner surface of the lid body 2.SOLUTION: In the electronic apparatus, a seating surface 13 spread around an opening 15 of the accommodation chamber to install the waterproof packing 4 and an inner circumferential surface 14 rising from an outer edge of the seating surface 13 while surrounding the seating surface 13 are formed in the casing 1. The waterproof packing 4 is formed from an elastic resin member 41 and a metal member 40 buried within the elastic resin member 41. A first projection 42 to be in press-contact with the seating surface 13 of the casing 1 and a second projection 43 to be in press-contact with the inner circumferential surface 14 of the casing 1 are formed on a surface of the elastic resin member 41. The metal member 40 is configured by overlapping two metal plates 5 and 6 and on one metal plate 6, a plurality of bent pieces 61 are formed which protrude towards a surface of the other metal plate 5. |
