An object of the invention is to provide a foldable electronic apparatus capable of exhibiting satisfactory acoustic characteristics even if the body is thinned and its internal space is made small. In an electronic apparatus according to the invention, a first casing (1) and a second casing (2) can be folded together along a bearing portion (3) and the front face and the back face of one of the first and second casings ((1) or (2)) are formed with respective sound emission holes (8) and (6) that are opposed to each other. A speaker (7) is provided at a position corresponding to the sound emission holes (8) and (6), and the front face of the other body ((2) or (1)) is formed with a through hole (9) that is opposed to the sound emission hole (8) in a state that the first and second casings (1) and (2) are folded together.
