ABSTRACT:
A laser module includes a semiconductor laser that emits laser light within a wavelength range of 350 to 450 nm, and hermetically sealing members, in which the semiconductor is sealed. The amount of organic adhesive utilized within the volume of the sealed sealing members is 1.0 g/ml or less, thereby causing a saturation concentration of outgas components generated from the adhesive to be less than 1000 ppm following a deaerating process. At least one optical component (e.g., a collimating lens) is adhesively fixed to a fixing member (e.g., a collimating lens holder) by inserting an adhesive composition including an alicyclic epoxy compound, a compound having an oxytanyl group, and a catalytic amount of an onium salt photoreaction initiator therebetween at an adhesive thickness of 0.05 μm or greater and 5 μm or less. Thereafter, the adhesive composition is cured by an activated energy beam to fix the optical component to the fixing member.
