LINE LIGHT SOURCE AND IMAGE SENSOR

PROBLEM TO BE SOLVED: To provide a line light source using a light guide body that enhances emission ununiformity due to its structure. SOLUTION: In the line light source structured to include the light guide body 3 made of a transparent member covered by a light guide body cover 2 and a light source 1 located in the vicinity, to make light emitted from the light source 1 incident onto the light guide body 3, and to diffuse the light by a diffusion part 4 drawn on the light guide body 3, even when inevitable illuminance ununiformity due to the component structure is caused, the diffusion part 4 to control light such as paint 35 is applied to the part causing the ununiformity so that the illumination uniformity can be improved.
