PROBLEM TO BE SOLVED: To provide a laser light source device in which fastening torque is ensured when a holder is fixed to a supporting substrate and a temperature regulation element is not damaged. SOLUTION: The laser light source device comprises a holder 43 for holding an LD 30 consisting of a laser diode (LD) 30, a PPLN 34 that outputs the second high frequency of laser light emitted from the LD 30, and a fiber Bragg grating 32 arranged between the LD 30 and the PPLN 34 and defining the range of wavelength of laser light, a holder 43 for holding the LD 30, a holder 40 for holding a PPLN 34, a supporting base 70 for fixing an LD holder 43 and the PPLN holder 40, and a first fixing mechanism for fixing and securing the PPLN holder 40 to an element 70 wherein the holders 40, 43 are fixed to the supporting base 70 such that Peltier elements 41, 44 and a resilient heat dissipation sheet 72 are held between the holders 40, 43 and the supporting base 70.
