Abstract
A light source device includes a package and a substrate. The package includes first and second electrodes. The first electrode has first and second parts separated from each other by a first separation region on a lower surface side of the first electrode while the first part is continuous with the second part on an upper surface side. The substrate includes a pair of wiring members. Lower surfaces of the first and second parts face and are mounted on an upper surface of one of the wiring members. A lower surface of the second electrode faces and is mounted on an upper surface of the other of the wiring members. A region of the substrate facing the first separation region has solder wettability lower than solder wettability of the upper surface of the one of the wiring members facing the first part and the second part of the first electrode.
