Abstract:
1. A laser module comprising: a semiconductor laser that emits laser light within a wavelength range of 350 to 450 nm; a sealing member, the interior of which is a sealed space filled with an atmosphere in which an organic gas component generated by a solid organic material is at a concentration of less than 1000 ppm, for sealing the semiconductor laser within the sealed atmosphere therein; at least one optical component within the sealing member; and a fixing member for fixing the at least one optical component; wherein an adhesive composition that includes an alicyclic epoxy compound having an epoxy group, a compound having an oxytanyl group, and a catalytic amount of an onium salt photoreaction initiator is inserted between the at least one optical component and the fixing member, then cured with an activated energy beam to fix the optical component to the fixing member.
