One object is to provide a lighting device having a large irradiation range at low cost. One object is to provide a lighting device with improved light extraction efficiency at low cost. The lighting device includes a light-transmitting base, a first light-transmitting electrode formed over almost the whole area of a surface of the light-transmitting base, an EL layer over the first light-transmitting electrode, and a second electrode over the EL layer. The light-transmitting base has a cylindrical shape, a conical shape, a prismatic shape, or a pyramidal shape whose bottom surface is the surface of the light-transmitting base.
