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 parts2each of which is provided with a light irradiating part21where multiple optical fibers4are thickly arranged in a line with light leading out end portions4aof the multiple optical fibers4forming a straight line and a columnar lens22arranged to extend along a direction of the line P in front of the light irradiating part21in pairs, and that irradiate line light LL that converges into a straight line, and a holding body3that 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 bores3a,3bare arranged to penetrate in order to monitor the work W, and that holds the light emitting parts2so that each optical axis face of the line light LL irradiated from each of the light emitting parts2crosses on a predetermined straight line.
