An electronic apparatus of the present invention includes a first case 1 including a keyboard 5 and a signal processing portion, a second case 2 including a liquid crystal display 21 that is capable of displaying visible information obtained by converting an input signal into a visible information signal in the signal processing portion, hinges 3 for rotatably supporting the first case 1 and the second case 2, and light source bodies 11, 12 that are capable of illuminating the keyboard 5 and located at both ends of the second case 2 in the axial direction of the hinges 3. With this configuration, the electronic apparatus can not only illuminate the input portion but also prevent light from entering the eyes of a user directly, thereby making it possible for the user to perform the input operation properly in a dark place.
