In a light guide body, a flat part is provided at an edge part of a fluorescent tube vicinal part (part that receives strong light), and a pear-skin texture pattern having a sine wave shape boundary is formed inside the flat part. Therefore, it is possible to alternately provide, along a direction to which the fluorescent tube extends, small pear-skin texture regions and small flat regions. In certain example embodiments, scattering intensity of the light guide body is set so that it becomes stronger gradually from the edge part close to the fluorescent tube toward the inside far from the fluorescent tube.
