Abstract
A light source device includes: a semiconductor laser; a coupling lens; a holder; and a photopolymerizable resin. The coupling lens converts laser light from the semiconductor laser to a light flux, the coupling lens having a first side and a second side opposite to the first side, the coupling lens having an outer peripheral surface connecting the first side and the second side. The holder holds the semiconductor laser and the coupling lens in a manner that the first side of the coupling lens confronts the semiconductor laser. A part of the photopolymerizable resin is provided between the outer peripheral surface of the coupling lens and the holder and another remaining part of the photopolymerizable resin protrudes from between the outer peripheral surface of the coupling lens and the holder in a direction defined from the first side to the second side, the photopolymerizable resin being cured to fix the coupling lens on the holder.
