ABSTRACT:
A semiconductor laser device1comprises: a heat sink20, in turn comprising a main cooler unit21, formed by joining metal members, a fluid channel30, formed inside the main cooler unit21, a cooling region23on an outer wall surface22, and a resin layer40, being continuously coated onto the outer wall surface22and an inner wall surface33with the exception of the cooling region23; and a semiconductor laser element80, positioned at the cooling region23with thermal contact with the outer wall surface22being maintained. By continuously coating the outer wall surface22and the inner wall surface33with the resin layer40with the exception of the cooling region23, prevention of corrosion near portions at which the outer wall surface and the inner wall surface contact each other is realized.
