To provide a flip electronic device in which even when rain water or the like enters therein to a certain extent, it is absorbed and hence an electric circuit therein is not affected. In the flip electronic device, slight clearances are formed between bearings (3a), (3b), (4a), (4b) for rotatably connecting first and second enclosures (1), (2), and cylindrical members (13), (14) formed coaxially with the bearings (3a), (3b), (4a), (4b), and hence rain water may enter through these clearances. Therefore, water-absorbing members (19), (20) are mounted to an end of a printed wiring assembly (17), and rain water entered through the clearances is absorbed by the water absorbing members (19), (20), so as to prevent an electric circuit located in the enclosure from being affected. <IMAGE>
