PROBLEM TO BE SOLVED: To provide a laser line generator with a large spreading angle, and a laser line generator module with the laser line generator integrated with a laser light source. SOLUTION: The laser line generator comprises an incident part 10 having an incidence plane 12 making incorporated laser beams into condensed light or parallel light, and an emission part 20 having a hollow cylindrical part 27 irradiating the incorporated laser beams linearly, or a hollow semicylindrical part 29 with the emission plane 22 side formed as a curved surface.
