A clamping jig for mounting semiconductor laser bars includes: multiple supporting bars for holding laser bars therebetween; a pair of supporting plates each of which has a mounting face for mounting the supporting bars in a row; a pressing member for pressing the supporting bars for holding the laser bar; pressing cover members for covering both ends of each supporting bar to prevent supporting bars from falling from the supporting plate; and a supporting frame for detachably supporting the supporting plates and pressing cover members. Each supporting bar is formed with a longitudinal length greater than the laser bar, within a predetermined length so as to be mounted within the supporting frame. Both of the pair of supporting plates may be mounted so as to face one another, or just one may be mounted with the pressing cover members being mounted on the supporting frame instead of the other supporting plate.
