ABSTRACT:
A waterproof structure for an electronic apparatus of the present invention includes keybuttons positioned such that their ends appear via holes formed in the casing of the apparatus. A circuit board is loaded with switches configured to selectively open or close when the keybuttons associated therewith are operated. A sheet member is formed of an elastic material and intervenes between the keybuttons and the circuit board. The sheet member includes, at least in its peripheral portion thereof, a seal portion for preventing water or similar liquid from entering the apparatus and reaching the surface of the circuit board. When the sheet member is pressed between the casing and the circuit board, the seal portion is at least partly pressed against the inside surface of the casing while being subject to a bending load.
