A semiconductor light-emitting device includes: a board including a front surface, a back surface facing an opposite side of the front surface, a first wiring pattern formed on the front surface, and a second wiring pattern formed on the side of the back surface with respect to the first wiring pattern; and a light-emitting element, a switching element, and a capacitor, which are electrically connected to one another by both the first wiring pattern and the second wiring pattern. Among the light-emitting element, the switching element, and the capacitor, a first predetermined element and a second predetermined element are arranged in a first direction and the second predetermined element and a third predetermined element are arranged in a second direction. The second wiring pattern forms a second current path opposite to a direction of a first current path. The second current path overlaps the first current path.
