PROBLEM TO BE SOLVED: To provide a semiconductor light-emitting device capable of preventing polarization of each laser element from being rotated before or after being mounted on a package, and to provide its manufacturing method. SOLUTION: A plurality of semiconductor laser elements 10a and 10b are formed on the same substrate 11. Further, Au plating 16 is formed on principal surfaces of the plurality of semiconductor laser elements 10a and 10b. Then, the plurality of semiconductor laser elements 10a and 10b are mounted on the package 22 using solder 18 applied onto the Au plating 16. Areas opposed across light emission areas of the semiconductor laser elements 10a and 10b are denoted as first and second areas. Then, an average value of the thickness of the Au plating 16 is made uneven in the first and second areas of the semiconductor laser elements 10a and 10b. COPYRIGHT: (C)2009,JPO&INPIT
