Abstract
In order to provide a line light irradiation device that can improve efficiency of condensing light with a compact size and that is almost free from unevenness of lighting, the line light irradiation device of the present claimed invention comprises multiple light emitting partseach of which is provided with a light irradiating partwhere multiple optical fibersare thickly arranged in a line with light leading out end portionsof the multiple optical fibersforming a straight line and a columnar lensarranged to extend along a direction of the line P in front of the light irradiating partin pairs, and that irradiate line light LL that converges into a straight line, and a holding bodythat is arranged to face to a work W as being an object on which the line light LL is to be irradiated, on which monitoring boresare arranged to penetrate in order to monitor the work W, and that holds the light emitting partsso that each optical axis face of the line light LL irradiated from each of the light emitting partscrosses on a predetermined straight line.
