Abstract
Semiconductor laser device Aincludes semiconductor laser element, switching elementhaving gate electrode, source electrodeand drain electrode, and support memberhaving conductive partthat forms a conduction path to switching elementand semiconductor laser elementand supports semiconductor laser elementand switching element. Conductive parthas front surface first sectionspaced apart from semiconductor laser element. Semiconductor laser device Aincludes at least one first wireconnected to source electrodeof switching elementand semiconductor laser elementand also at least one second wireconnected to source electrodeof switching elementand front surface first sectionof conductive part. Such an arrangement reduces the inductance component of semiconductor laser device A
