Abstract
A two-beam semiconductor laser deviceincludes: a two-beam semiconductor element LDC having a first and a second semiconductor laser elements LDand LDthat can be driven independently and that are formed integrally on a substrate; and a submounthaving, mounted on a front part thereof, the two-beam semiconductor laser element LDC with the light-emitting face thereof directed forward and having a first and a second electrode padsandconnected to electrodesandof the first and second semiconductor laser element LDand LDby being kept in contact therewith. The first and second electrode padsandare formed to extend farther behind the two-beam semiconductor laser element LDC, and wiresandare wire-bonded behind the two-beam semiconductor laser element LDC.
