An electronic book includes a main body and a pivot member rotatably mounted to the main body. The main body includes an electrophoretic display, and defines a first receiving space in a bottom of the main body. The pivot member includes a base plate received in the first receiving space and a lighting body mounted to the base plate. When the electronic book is used, the pivot member is rotated relative to the main body, the base plate is moved out of the first receiving space to be positioned above the electrophoretic display, and then the lighting body is turned on to light the electrophoretic display.
