Abstract
The light source device includes a first light source, a second light source, and a substrate including a base member. A first wiring and a second wiring are disposed on the substrate. The first wiring has a connection part including connection parts such that the first light source is electrically connected in series and a connection part including connection parts such that the second light source is electrically connected in series. The base member is provided with at least one through-hole at each portion where the connection parts of the connection parts are disposed, and includes a protrusion in a vicinity of the through-hole such that the protrusion protrudes along a surface of the base member in a direction intersecting the first wiring. The second wiring includes at least one detour path in a vicinity of the protrusion, detouring around the through-hole with an insulation distance from the through-hole.
